HELP!!!!!!!

Ok so I've been with my boyfriend for two years, we got pregnant last year, and if it wasn't for him I wouldn't be here today, we lost the baby. We haven't been the same since. There used to be so much fire and passion between us, I'm a 24 year old mother of a 4 year old, and I don't know what to do with my boyfriend. I have to keep communication open with my baby girls dad and his family because of child custody issues, and my boyfriend just doesn't understand that. I seriously need an outsiders point of view?
