I was once in a really abusive relationship, where I was on the receiving end. I learned a few things from my experience.

There is nothing you can do to get him to trust you. Either he trusts you, or he does not. If he does not trust you, then you do not have a healthy relationship.

Also, you can try and try all you want to make the relationship work. But if both people don't work, and both don't want it, then you can put your all into it and it won't make a difference.

Finally, each person has to own their own mental illness, issues, paranoia, or whatever else is going on. If he is not interested in dealing with his own issues, and wants to constantly blame you, then you don't have a relationship.

I know what it's like. I wanted that relationship to work out so much, especially because we had a child together. But in the end, I had to accept the hard reality that it would not work, and that it would be dangerous for me to stay in it.

I think your best move would be to get out, get far away, and not talk to him anymore. No calls, no texts, no emails, no social networking, no explaining. Of course, this is only if he is unwilling to own and deal with his issues.

I know how rough it can be. Best of luck.
