A lot of Matt's fear, he says, is "based on what I've seen in my family in the past." Some of that family dynamic will play out on-air, as the preview shows Matt telling his dad, "When I needed you, you weren't there."
"I don't want to make those same mistakes that caused my family to be torn apart," Matt says, before his mom tells him that love "is not the end-all, be-all."
Matt, Rachael, Michelle and Bri all break down in tears in the clip, with Matt saying, "I feel like everything I was working towards is starting to crumble. I don't know how I go on. How do you go on from there?"
The clip ends with Matt telling Chris Harrison that he's not OK, and admitting that he doesn't know if he can continue with the show.
