Honestly, if he is making this kind of a permanent change in his life, he might be thinking he better really figure out what he really wants out of life and a relationship. Maybe what he is doing is just making sure he doesn't jump into another relationship that he just wants to get out of later. I do agree that she kind of put herself in a place where he was already unstable in relationships- just happened to be with her.

Maybe this is a step in the right direction from him.
