I was with a man who I considered my best friend. He left his wife & soon thereafter we started a really intense relationship. We quickly moved in together & started making a life together. When we hit the one year mark things went south really fast. I felt that he was selfish. He had allowed his wife & 3 kids to be evicted from their home because he withheld 2 months of child support. I was shocked at what he didn't seem to care about. He turned into a monster within a matter of a week & left me to go back to his wife. Within 5 days of that decision he wanted to come back to me & I allowed him to. Within 5 more days he was back with her. He doesn't care whose life he ruins. When he was home for that brief period he had divorce papers served on her. I just don't know what happened but feel like I'm dealing with someone who is very mentally ill. He doesn't care that once again he's left me all alone. Any advice would be appreciated .
