Oh Charlotte- you deserve so much better, as does your child.
It doesn’t matter that the pregnancy was planned, what matters is the way he is treating you.
You’re no longer his girlfriend and drinking pal (drink is irrelevant to this as prior to being pregnant that’s your own business) you’re the mother to his child now. You’ll never be the same again. I think every mum will tell you the same.
His insults are nasty. Really vile and I hope I’m not overreaching when I suggest that he’s zeroing in on your biggest insecurities and using them to manipulate you and hurt you to the greatest extent he can.
That’s not your hormones; that’s sadistic and deliberate cruelty.
Like many other PPs I’ve had the same. You think it’s bad now- that he’s not the Centre of your world anymore- wait until you have a child who will always come before him.
You need a break from him. He either leaves and goes elsewhere (I’m going to be realistic and suggest you won’t leave him the first time- much as I’d like you to, I’m a cynic and realistic and understand how hard it is) or you force him.
Are you close to his family? If so, tell them. If he was my son I’d drag him out by his ear and he’d have the bollocking of his life.
You need support irl. Tell your family, tell women’s aid and ask for the advice of the police.
Not au fair with uk laws but if you are in a domestic abuse situation (which you are) as everything is in your name, he will be the one going.
Being a single mum is hard, but not impossible. You sound terrific, but completely overwhelmed. Let people help you and one day you’ll look back and congratulate yourself for doing this. It can be hard to see the Forest from the trees.
Take care
