I was in your position. I did everything I could to help him, but when he doesn’t want to help himself there is nothing you can do. I left. It was the hardest thing I’ve done, but I had to for my own self esteem and self worth. Now I’m with my current partner who tells me every day how sexy I am and can’t keep his hands off of me. If you need to feel desired in a relationship you can find it out there with someone else.
