Fiancé doesn't get on with my parents

I'll simplify this to save time but please know there is so much more.
In short, I lived independently in the North for years, he's always lived with his parents.
I moved down south to his parents house 3 years ago, I fell pregnant, parents kicked me out, I was homeless for 2 months and I've since been housed and now have my little boy, partner now lives with me. BUT.
We have done nothing but argue and despite repeatedly asking not to do it infront of LO, he still starts and godes.
My parents (who are split up and don't talk to each other) do not understand why he didn't move out with me when I was homeless, smokes Green, is lazy around the house and uses LO as a trophy baby. SO doesn't understand what their problems are since he's financially supported me and has now moved in so doesn't see me being homeless as an issue anymore.
He lives with me but dictates what I do. My step mum has asked me to house sit for a week, he said no despite me stating he would still see LO. My dad offered for me and LO to go for a mini break, he said no. I have 5 family members, 4 of which live 4 hours away and he's fallen out with all of them. He's now told them all they can't come in MY house. His whole family live a max 15 minutes away and I'm still healing from being kicked out and things said before, during and after pregnancy.
Its now a major issue and I can't talk about my family at all, I cant go away for any amount of time, he books things with his family and LO but doesn't tell me and still expects me to go.
He smoked so much 🌱 that he was unable to look after LO and I couldn't wake him up and ended up doing a 48hr run with LO.
I've told him I'm unhappy and the issue with my parents can be sorted by apologising but he won't.
Hes got a 7yo daughter from a previous relationship that he fought in the courts for who he doesn't do much with other than dumping her with one of his sisters and then wants people to think he's a brilliant dad 🙄
I'm at my wits end with this guy, he just doesn't see he's doing anything wrong and stopping my family seeing their grandchild, which I'd never dream of doing because he forces me to apologise which I do every single time despite it not being my fault and being called every name under the sun, is not my fault.
Everything's been handed to him and he's a spoilt brat, I've told him that too.
I don't know what I'm posting this for tbh. Maybe just a sound board but I could do with something positive being said from someone, anyone instead of being told I'm a failing mother.
I dunno, maybe it's my fault but when I ask him he can't come up with a plausible reason why I should apologise whereas I've got plenty.
He'll just storm out the room and spend hours with his friends smoking green. 🌱
