Thank you for all the input. He has small kids and is living with his ex just so that she doesn't take the kids. He completely supports her, mentally and financially.
It doesn't bother me because I know they are done. What bothers me is that he doesn't want to move because kids have day care, etc that he doesn't have any to disrupt.

I wouldn't mind moving but he just doesn't seem like he is ready because I have tried to end this relationship before and he is afraid to bring kids back in.
DBTDiva, I may have to take your advice ,be strong and walk away.. Yes, I love him but I am too unhappy right now.
