During an interview with Esquire in 2023, Matt Rife opened up on his dating life and said:

“I kind of hate dating. I know I am just in my mid-to-late 20s, but still, I do want a wife and a family and a prominent home life that makes me feel comfortable, safe, and is my peace. But when I'm touring six days a week, 52 weeks out of the year, it's incredibly hard to maintain a relationship.”

He added:

“I do meet women who are fantastic human beings that I'm like, “Wow, you're such a lovely person. You're beautiful. You're sweet, you're kind, you'd be an excellent mother and excellent wife, excellent girlfriend, you check all these boxes, but I might not be in a position right now to fulfill your needs as a responsible boyfriend.” So I wonder if I am missing out on wonderful people, you know?”
