Where Im At

My story starts in a way I'm not proud of. I was in a bad relationship with a guy who was verbaly abusive and trashed my things. I was afraid to leave. I got a job at a factory and my supervisor was in the same boat only he was afriad to leave because of his childrens saftey. His wife is bipolar and refuses medication. We kind of fell in eachothers laps and he finally left her for me. We lived together and were so happy. Then he started to get weird and i started to try to make him happy. nothing seemed to work and he kept telling me i was his perfect woman. In the end he cheated on me with his ex and told me we werent ment to be together and moved her in the next day. While i was now in my mothers house with nothing. He calls two days later and tells me he wants me back and he doesnt love her he was just doing it for the kids. He said that she agreed to be medicated if they were together but he couldnt do it anymore. He said that were soulmates and we were ment to be together. I know its stupid but i felt that way the whole time and even though he did something horrible i cant help but to want to be with him because i do feel the same way. Then i discused it with my family and they will not support my dicision and i know ill loose there respect if i go back. My family is important but i just know i want to be with him. What do i do?
