I’m not disagreeing with anyone else, but maybe your attitude toward yourself has changed as well which could also cause him to be more attentive. If you gave off vibes of disliking your body perhaps he picked up on it. You might be more confident now and that is showing to him. I feel more able to move around and enjoy myself than I did before although I still have a lot more to lose. These are simply some thoughts on my part. It’s sad if he just didn’t find you attractive and avoided you because you are the same person inside as you say.
It’s great that you are working on things in therapy. I didn’t feel like I deserved anything from anyone for a long time, but therapy did help. I also did everything for my husband for a very long time and thought that I had to be super wife. We split chores and stuff much more equitably now.
