The two talked about finances, and it turned into a huge argument."This argument arose over an issue that, from what I could gather, was as if he felt somewhat belittled by this whole financial matter. And then, from there, a truly nasty argument came up, in which he said some very, very, very mean things. Back then, I loved him so much. Truly, so much. It was very hard because I had already spoken to my son about this, and I had already told him that Nicola was coming," shared Karen.Love Is Blind: Italy Reunion: Karen recalls how she booked a five-star hotel for Nicola, and their "finances" discussion led to an intense argument View this post on Instagram Instagram PostLove Is Blind: Italy hosts recalled Nicola and Karen getting married.

Because of the distance, she booked a hotel for him. View this post on Instagram Instagram Post"While we were talking and organizing this, these three days in Rome, he said, "Karen, don't get anything fancy. I mean, don't worry. Get something normal. And I still got a hotel that was...five stars. Of course, very nice because I didn't care."Soon, they got into an argument over their financial matter. At that time, Nicola said some harsh words. Despite her loving him very much, it was hard for her. It was because she had already told her son that Nicola was coming."And at that moment we had this argument. I was expecting him to at least...you know, a call to apologize the next day, or to figure out how to have a conversation," added Karen.But there was no call or apology from Nicola.

He added that he took Karen's talk about finance the wrong way.To learn more about what Nicola shared, head to Netflix and stream Love Is Blind: Italy Reunion.
