Breakups

I feel really really depressed because the father of my unborn child told me it wasn't working out between us because his family didn't like me. I don't talk to his family because I have no way of getting ahold of them. They aren't excited as my family about the baby and always said I was lying to him to keep him with me. I'm 6 months pregnant and I feel so alone and unloved because he left me so suddenly. I try to stay positive but it seems to get harder everyday. I don't know what to do. Any advice on how to stay calm and be happy so the baby is okay?
