I have been in a basically non exclusive relationship for some time now (5 years)It started as pretty much friends with benefits but it has grown tremendously. It's pretty much a relationship without the commitment. We see each other 5-6 days out of the week, talk everyday, go to church together, etc. However he will not commit to me. He also has been seeing his ex on and off for some time now. However their relationship is much more dysfunctional. They argue all the time, he will block her phone number for long periods of time. I think he won't commit to me because he doesn't necessarily want to be with his ex but I don't think he wants to see her happy with anyone else. She is literally crazy about him. She calls him back to back when he ignores her, emails him constantly when her number is blocked, and will literally do anything for him because "she just wants him to love her even more." Me on the other hand wants commitments from him but I feel I will never get that as long as his ex is in the picture. One reason I haven't walked away is because I feel like I would be letting her have everything that I want. I know he sounds like an asshole but he really isn't. He treats her that way because well according to him she has a very bad attitude and is very selfish. What do I do?
