I think he was attracted to her in the very beginning. It seems like he got the ick from her but maybe they stay together for the show? If they broke up, no more TLC. For some reason I don’t think he’s a cuck or into being humiliated. He could have found that easily on a fetish site but instead he was on a sugar baby site. He also asks her to stop doing that and even told their therapist that’s why he doesn’t want to have sex with her, because of the way she treats him. It makes the most sense that at this point they don’t want to break up because that would probably mean quitting the show. So their relationship has become more a business partership.

Wasn’t she spending time at her exes house, and he wanted them to move away, and for her to cut ties with him even though he was the father of her children? She refused to do that and they kept fighting about it. I don’t remember the source but I read that is why they broke up after he got here.
