Ladies, Ive been seeing this guy for a month and a half, he practically lived with me while we were together, and we recently broke up and I thought Id be ok but I'm not. I left him because my mom made my life a living hell. Im a wreck. I cant sleep. Im not happy. I just want him back. I apologized For leaving and told him I want him back but he won't talk to me. What should I do..
