S.O.S nasty baby daddies

So I’m 18 weeks and 4 days 😊

Since I was 11 weeks I’ve been on my own, the father decided he’d had enough of me being emotional and getting upset when he’d leave me at home to go drinking and then wake me up at 5:30 in the morning when my morning sickness had been keeping me up all night 🙄 anyway he’s nothing but nasty to me, doesn’t come to any appointments, is refusing to give me a few of my things back and has said unless I stay in hospital for the first few nights after the baby is born he’s not helping because I live with my parents and he thinks that they will be rude which they won’t I’m only here until I can afford to move back out.. he’s also threatened to take the baby away from me because I decided I’d rather it have my last name and he’s not happy about it..

I just want to know what I could do to make this easier on myself without giving into to his every demand about the baby, I’m constantly stressed which is making me sick and I’m barely sleeping, he’s already got a four year old son and he just took him from his Mum because she decided to move in with her boyfriend... I know he’ll end up just taking the baby from me and I’m petrified! I feel like I’m just an incubator I’m not excited about any part of it at all anymore and I feel so guilty! 😭
