I'm so sorry. I was dating a guy like that. I miss him a lot and sometimes I feel like I'm still in love with him, then I realize he hasn't changed and soon he will be in jail. I have a daughter and boyfriend that I love more than anything. That boy is still crazy about me but I have to do whats best for my daughter. I tried helping him but I'm not a mother of two and I can't deal with it anymore.
No one should be faced with the responsibility of another and that is what he asked you to do. I think you know it's not your fault but you can't blame yourself for no believing him. I think you do do that. It wasn't your job.
