In 1990, Ridge's first wife, Caroline, began counseling with Taylor after discovering that she was dying of leukemia. Caroline asked both Taylor and Brooke to look in on Ridge after she died.

At one point, Taylor dated Ridge and Storm, Brooke's brother, at the same time. Taylor later took up with her ex-husband, Blake Hayes, who still suffered from a medical condition that caused violent outbursts. His feelings toward Taylor were obsessive. He rented an apartment across the street from Taylor and spied on her with binoculars. He was jealous of Ridge's presence in her life. Blake made several efforts to come between Ridge and Taylor -- showing Stephanie's videotape of Brooke and Ridge making love in the Forrester Lab after developing "BeLieF," then discovering Caroline's twin sister, Karen, and trying to recreate Caroline to try to stir feelings in Ridge. Eventually, Blake and Taylor parted ways and he returned to Texas.

While Taylor vacationed in St Thomas, Ridge followed her there and proposed. Despite discovering that she was pregnant, Brooke failed to stop the wedding. Unknown to everyone, Sheila Carter interfered with blood samples of a paternity test that revealed Ridge to be Bridget's father. Years later, a second test proved that Eric was, in fact, Bridget's father.

Taylor's mentor, James Warwick became her patient in 1992. Taylor's respect and admiration for James was misinterpreted by Ridge, who suspected the two of having an affair. James and Taylor were at Big Bear together when an earthquake occurred. The wintry cold threatened to end the lives of the two psychiatrists, who struggled to wait for help. James confessed to Taylor that he didn't want to die a virgin. Out of compassion and fondness, Taylor obliged.

In 1994, Taylor was presumed dead after her plane crashed while returning from a medical conference in the Middle East. Ridge turned to Brooke during his loss. As the two grew to love each other once more, Prince Omar was in Morocco pampering his "Princess Laila," a woman he found beaten at the airport and suffering from amnesia -- it was Taylor! Ridge and Brooke had a grand beach wedding, with the bride arriving on horseback. Prince Omar kept Taylor's true identity from her and planned to marry her. Seeing how happy Ridge was, and in order to spare him more pain, Taylor decided to stay with Omar as his princess. Taylor was forced to return to L.A. after her father, Jack, suffered a heart attack. Soon everyone learned that Taylor was alive.

For years, Ridge remained undecided between Brooke and Taylor, marrying one and divorcing the other. Eric once made a pass at Taylor, who gently turned him down because of her friendship with Stephanie. Grant Chambers' advances were also turned away. In 1998, Taylor's pregnancy was threatened and she went along with Thorne's plan to pretend the baby was his after the stress involving Ridge and Brooke caused her to have stomach pains. When Ridge learned the truth, he committed himself to Taylor and his family. In 1999, Taylor's work colleague, Pierce Peterson, began developing feelings for her, however, Ridge and Taylor remained strong after she became pregnant again with the twins. Exposure to an infected patient caused Taylor to have tuberculosis. She made the life-threatening decision not to treat her condition with the antibiotics that would compromise the health of her unborn babies. Very weak and close to death, Taylor gave birth to Steffy and Phoebe.

Brooke hired Morgan to design at Forrester Creations. Stephanie had forced Morgan to have an abortion after she became pregnant with Ridge when they were teenagers. After becoming best friends with Taylor, Morgan tricked Ridge into sleeping with her and she became pregnant with Ridge's baby again. A confrontation between Taylor and Morgan led to a struggle, causing Morgan to fall off Ridge and Taylor's balcony. Morgan's baby died. In an act of revenge, Morgan kidnapped Steffy, whom Ridge and Taylor believed to have been the victim of a shark attack after losing her out at sea during a storm. After Taylor discovered Steffy was alive, Morgan held Taylor prisoner in a secret room of her house. When Ridge pieced together the truth, he drove his car through Morgan's living room and reunited with his family.

After years of fighting for her family and building her life with Ridge, Taylor returned to work with Dr. Nunez. Her first patient was be Antonio Dominguez, Kristen's new boyfriend. Taylor put her career in jeopardy when she threatened to tell Kristen he was HIV positive. Thorne and Brooke's marriage crumbled when Brooke developed a renewed interest in Ridge. Brooke tried to her hardest to seduce Ridge again, but he refused to betray his wife. Later when Brooke was having a personal crisis, Ridge took advantage of the situation to try to take control of Forrester Creations. Rick and Deacon stopped him, and Ridge was forced out of the company completely. He then began working for Massimo Marone and hated most of his family, especially his little brother, Rick, and his wife, Amber. This became a problem when Taylor began helping Amber. First, she helped her get into a drug rehab center when she was addicted to pain killers. She then helped her again when she needed a place to stay while Amber and Rick were separated. After all the horrible things that had happened to Amber, Taylor was the only one who believed that Amber was innocent. Taylor's faith and hospitality towards Amber caused problems in her marriage to Ridge.

While Amber was staying in Ridge and Taylor's home, she was kidnapped by the person who was causing all the problems in her life, Sheila Carter. Sheila attempted to kill Amber, but was stopped by Massimo and Stephanie. Sheila did get away, though, and drove to Eric's house and held him at gunpoint. After finding out Sheila was on the loose, Taylor realized that Eric could be in danger, so she went over to his house and was held at gunpoint, too. While Taylor was trying to convince Sheila to drop the gun, Brooke walked in and a struggle between everyone erupted. In the end, Brooke and Taylor were shot. Taylor and Brooke were transported to the hospital, and Taylor was immediately rushed into emergency surgery. Taylor survived the surgery and remained in critical condition. She regained consciousness long enough to say goodbye to her family. She died peacefully in her husband's arms...

...or so they thought. In early 2005, as Bridget and Nick were about to say, "I do," guests heard the sound of a woman screaming. When Ridge went to check it out, he came face-to-face with Taylor, only to have two men strong-arm her away. She was finally able to reveal herself to Ridge, who was overjoyed at having her back in his life. Taylor explained to him that they had only thought she was dead, but Omar had spirited her away to his home, even planting a false bust of her in the casket to fool them all, and she slowly recovered under his care. Taylor was shocked to learn, though, that Ridge had not only married, but fathered a child with Brooke during her time away. Things were soon further complicated when an old friend, Dante, returned to town. Taylor soothed Ridge's jealousy by explaining that Dante had been instrumental in her getting away from Omar.

Ridge and Taylor seemed to be getting back together, even though he vacillated between her and Brooke, until Stephanie had a heart attack, prompting him and Taylor to renew their vows. Once it was revealed that Stephanie faked her heart attack, Taylor couldn't stop wondering if Ridge was with her for the right reasons. While Ridge was on an extended trip out of town, Taylor shared a kiss with Hector. Although she pushed Hector away, she felt guilty and confessed her transgression to Ridge when he came home. Not only did she confess her kiss with Hector, she also told him the truth about having slept with James many years earlier. Although Ridge was willing to forgive her infidelity, he stated that he could not forgive the hypocritical attitude he felt she had held Brooke up to throughout the years. Reluctantly, Taylor had annulment papers drawn up.

Despondent, Taylor found solace in wine. Hector rescued her after Taylor got in an accident caused by drinking and driving. He tried to counsel her to look to the positive things in her life. Hector and Taylor became friends but Taylor did not stop drinking. One night she found herself alone and at the same bar as Nick, who was also drinking. They end up passed out together on the Shady Marlin, where Brooke found them.

Taylor's life continued to spiral out of control when Stephanie, who had always supported her, turned her support towards Brooke, actually giving her 50% of the company. This was too much for Taylor and she confronted Stephanie, accusing her of an unnatural relationship with Ridge. Stephanie was shocked and furious at Taylor's words and slapped her. Taylor told Stephanie that she would live to regret that.

Taylor was drinking alone one night and received a call from her daughter, Phoebe, asking for her help. She was broken down on PCH and frightened because a scruffy man had shown up at her car. Taylor ran to her aid even though she had been drinking. The night was dark and foggy and she arrived at the car at the same time that Darla Forrester was trying to get the lug nut off Phoebe's tire. Darla, using all her strength, pulled, and as the lug nut released, she flew back into oncoming traffic directly into the front of Taylor's car. Darla died from the trauma and Taylor felt responsible and guilt-ridden for her death. Taylor's immediate reaction was to confess her part, but when her daughter and Hector begged her not to, she conceded and kept it to herself.

Trying to help, she became close to Thorne and his daughter. Stephanie knew the truth about Darla's death, but when she realized that Thorne was becoming happy again, she supported the relationship and warned Taylor not to reveal the truth. When Thorne proposed marriage to Taylor, the pressure became too much and Taylor confessed. Storm Logan came to town to represent her, but Taylor wanted to tell the truth and plead guilty. Although initially feeling deep rage and betrayal towards Taylor, circumstances surrounding the incident became known and Thorne pleaded with the court to find her not guilty. When the verdict was announced, Taylor was found not guilty.

Stephanie started opening up to Taylor about her abuse and Taylor informed her family of Stephanie's past and encouraged her to visit her mother. Taylor became aware of Nick's barely controlled rage and started to counsel him in an unofficial way. On New Year's Eve, Taylor visited her "patient," Nick, and he surprised her with a kiss.

Alexandria ran away after hearing from Hope how her mother had died. In a freak coincidence, Hope was found on PCH, luckily before harm came to her. The family gathered around Ally to try to explain things in a better way. Ally appeared to understand, but later colored on a picture of Taylor and ripped Taylor's wedding dress to shreds. Thorne and Taylor postponed their wedding, hoping Ally would come around. She didn't, so Taylor broke off their engagement, found Nick, and told him she was not going to be marrying Thorne.

Nick and Taylor began seeing each other, and on Valentines Day, they had a romantic evening. On a romantic night aboard the Shady Marlin, it was hit by another boat and Taylor was injured. At the hospital, Nick told Taylor he though he was falling for her. Stephanie and Jackie were opposed to the pairing and told Nick not to get involved with Taylor because he would always love Brooke. In spite of pressure from others to part, they became engaged. Nick wanted to elope, but Taylor wanted to wait for their family to be present.

Brooke came back from Australia and immediately began a campaign to get Nick back. Taylor told Nick that she wanted to give him a child, but was unsuccessful in getting pregnant. Taylor sought medical advice and, after testing, Bridget informed Taylor that her eggs weren't viable and that in vitro fertilization was their only option. Brooke, unwilling to give up on a life with Nick, found out Taylor was infertile and decided to have her eggs tested to see if she could give Nick a child. Right before Taylor and Nick were married, they were informed a donor had been found and Taylor went through the IVF procedure.

While Taylor blossomed in her pregnancy, unknown to her, Bridget began to suspect that the eggs used to fertilize Taylor were actually her mother, Brooke's. Bridget told Nick her fears and said they should wait until the baby was born to find out who the biological mother was. At Taylor's baby shower, she went into early labor and the baby was born ill with very little in the way of an immune system and needing a bone marrow transplant from the egg donor, since Nick was not a suitable donor. Bridget determined that person was her mother. Taylor and Brooke were told the truth, and Brooke was willing and happy to go through the procedure for Baby Jack. Even Brooke's willingness to relinquish her rights to Baby Jack were not enough to cure Taylor's fear and frustration that Brooke was her son's biological mother. Her joy in her newborn son was diminished because of Brooke's involvement and she began to have trouble bonding with Jack. Although Brooke promised not to interfere with Taylor and Nick raising Jack, she was having a hard time staying away and turned to Nick for help incorporating herself into Jack's life. Ridge and Taylor were firmly against it and, after a rough start, Taylor began to bond with Jack.

Nick met Brooke at Insomnia to talk about the problems Taylor was having emotionally and with the baby. Unfortunately, Taylor saw them together and all her insecurities were enhanced. Things didn't improve when Nick started referring to Brooke as Jack's mother, and Jackie encouraged him to be with Brooke. Taylor, a recovering alcoholic, was tempted to soothe her anxieties with a glass of wine. One morning she poured herself some, but forced herself not to take a drink. Brooke chose that moment to drop by on an unannounced visit, smelled the alcohol, and assumed Taylor was drinking. Brooke snatched Jack from home and delivered him to Nick.

Taylor's life continued to spin out of control when the people close to them found out that Brooke was Jack's biological mother and she felt that no one was supporting her. Jackie questioned her on how she was going to raise Jack when every time she looked at him she would see Brooke. Taylor began to hallucinate, seeing Brooke in her house with Jack, in a negligee. She found that alcohol would take the hallucinations away. Nick tried to reinforce that Jack was theirs, but continued to see Brooke to discuss Taylor and "their" child. Rick discovered Taylor was drinking and gave her his support. Nick decided to call Dr. Warrick in to help Taylor through her emotional problems. During counseling, Nick couldn't deny that he still had feelings for Brooke and decided to tell Taylor. When Taylor heard that although he had feelings for Brooke he would remain dedicated to her, she'd had enough, moved out, and started divorce proceedings.

Rick visited her in her home and reassured Taylor of his support then he kissed her. Taylor, feeling more stable, went to pick up Jack, but Nick wouldn't allow it because she had abandoned them both. Despite misgivings from Nick and Brooke, Taylor took Jack to live with her. Nick, feeling he had no other option because of Taylor's drinking, filed for custody. The judge walked in on Taylor, who lost it and attacked Brooke. Later she interrupted him and began a verbal assault on Brooke and, as a result, Nick was awarded temporary custody.

Taylor became despondent and began drinking heavily. Rick visited often and their visits became filled with passionate kisses. Taylor tried to keep him at a distance, but was grateful for his support. Brooke was angry and wanted them to break up; she threatened that if they didn't, she would make sure Taylor didn't get custody of Jack. Rick stood by Taylor and she found a certain amount of gratification in the fact that it bothered Brooke. Taylor, through counseling and AA, got her life together and when they went back to court, she and Nick received joint custody.

Phoebe returned home and discovered that her mother and her former boyfriend, Rick, were involved. Taylor told Phoebe she would end the relationship, but Phoebe decided that her mother's happiness was more important. So Rick gave Taylor an engagement ring in front of Brooke, and Taylor and he happily left to return home to make love for the first time. Steffy gave her mother her blessing, telling her to enjoy the wild side. When Rick took Taylor to Bridget and Nick's wedding, Brooke was furious and told Taylor how inappropriate she thought it was for her to be there.

After that, Taylor and Rick's relationship continued although they were rarely seen. A tired, frustrated Taylor told Rick that she didn't know what else to do to make her son happy. He wasn't sleeping and when he cried, which was often, she couldn't soothe him. After a lot of soul-searching, Taylor decided that her son's happiness was most important and, after speaking with Nick, asked Brooke if she would raise her son, Jack.
