Almost has given you some very sound advice here.
Shortly after my divorce, I became naively involved with a sociopathic addict. I thought I could help him, DUH!
He committed many crimes while he was involved with me and when I tried to extricate myself from him, he turned violent stalker. Even after he was imprisoned for breaking into my house with a gun, I still felt compassion and some sort of responsibility. That was 8 years ago. Now I see how confused my thinking was. It is frightening to be so vulnerable that you still want to "run into his arms" despite the unacceptable conduct of a criminal.
Please remove yourself and all contact with this man. After you have some time and distance from the situation, you will think more clearly.....and, be appalled, as I am that you subjected yourself to such a character!
