I got to the pretty much the same conclusion myself. Leaving him alone. I have been already going on dates for months now, not really successfully still, but who knows? I can't wait for someone who does not want me. We did broke up, even if it wasn't that obvious or explicitly said.

Divine1966, you remember my previous posts! Yes, it wasn't good relationship but it had its positive sides, at least for me. I am not easy person to be with, otherwise I wouldn't ask for help and had many therapists over the years. So dating me can be a lot and finding someone I like that much also isn't easy. I understand that with this person it's pretty much over. I believe him when he talks about his situation at home, because he does not lie, but I am really tired of chasing someone who does not want me.
You are right, he does not want help. He could have help, but he finds reasons not to get it. If his mother screams against when he wants to hire help, he should be able to explain her why that is necessary, not give up and feel like a victim. It's not my battle, neither I am invited. You are right, I am done.
