I think that it's important to some sorts of people to have a "hook" - something they can be unhappy with about their partners.
It wasn't just me. My ex had a giant hole in himself that he was trying to fill, and always looking for the next thing to make him feel better. Projects, adventures, remodeling, eventually affairs - all attempts to make things "better" in a way that might make him feel better. He could never just be happy with what he had - which was a LOT! Thankfully I never really let his criticisms of my body affect me - I knew how crazy they were.
Funny, even though my thighs are definitely fat now (they weren't then, at all) it has not been an issue with the partners I've had since my divorce.
