Idk what to do leave husband keep the baby or leave husband put baby up for adoption

So a little back story.... I have been married to my husband for 4 years together for 6 we met when we were 20 and I had a son from a previous relationship in high school. We moved in together fast and got pregnant with our daughter fast but our relationship was perfect. After we had our daughter we moved to his home town and I became a stay at home mom and we got married. I feel like this changed our relationship completely. I kept telling myself it would get better but it never did. I got pregnant again and it ended in a missed miscarriage and it was devastating for me but to him it was nothing. We ended up getting pregnant again right after that and had a second daughter... all my pregnancy’s by the way we’re on birth control of some type 😂 I’m immune! Well after our second daughter was born he got worse to the point of calling me names telling me I’m worthless that I never put out my maid duties suck well that’s all BS because our house is always clean my kids always are happy and healthy besides normal kid tantrums. I’m not perfect by any means but I don’t deserve this. It’s got to the point that he works as much as possible when he’s home he’s on the phone with coworkers. Weekends he sits around and drinks beer and doesn’t help me with anything. If I’m sick god forbid he will bitch at me like a woman that I’m slacking and that I’m fine. If I have the flu I get up and do my normal duties I have no sick days I get no rest. I have no one in his home town to help me. Well now I’m pregnant again literally off sex 1 time that month while having the iud 🤦‍♀️ sex with him lately is me forcing to do it so he doesn’t be an ass all day to me, even tho he still will be a ass all day to me. So now I have baby #4 on the way and a shitty as fuck marriage. He’s not even a great dad he never helps. I am the one doing parenting 24/7 round the clock while he simply plays with the kids every so often. I do not believe in abortion at all it’s totally out of the question. So I’m stuck on giving the baby up for adoption or keeping him/her and just being a single mom of 4. But when we split I have no money, no job, no house, no vehicle... literally everything is his since he wanted me to be a stay at home mom. I’d have to go back to my home town and live with my parents and get back on my feet but I’ll be doing that with my 3 kids anyway I just don’t know what I should do about 4 kids. I know it would kill me to give the baby up but everyone in my family says we don’t need another one. My own best friend told me the same thing. His family is all on board but they don’t know how are marriage and his parenting really is like. I know he would be ok with adoption because he didn’t want another child he doesn’t want another child.
