Baby daddy drama

Hey guys. I'm having some baby daddy drama and i don't know if it's the hormones or what it is but I'm kinda just sad. He treats me like shit and is always telling me what I can and can't do but he also isn't with me or even helping take care of me. I'm very very sick I have extreme morning sickness and I just want him around... I don't know. Even tho he's mean sometimes I just want to hangout with him. We use to be best friends and hangout and live together and be together all the time and now since I'm pregnant he's switched and just weird. He drinks a lot, one second he's going off on me, the next he's telling me he wants me to do this and not do that. And he had the nerve to ask for a blood test even tho he knows he's the only person I've been with. It just kind of hurts. I'm fine distancing myself and staying away for the sake of me and my baby but sometimes I feel week and just want him to hold me :(
