I'm glad you're ok OP.
So... as far as he knows, you left last night with a head injury and haven't been seen since, and he's not tried to contact you or find you?
That says it all.
I am sorry if what I'm going to say now is painful, but please think very hard about whether carrying on with this pregnancy is the right thing for you, or a baby.
You will never be free of him.
Last night was his reaction to you daring to want to walk away from him for some space in your own home. You were left in no doubt that you are not allowed to do that in this man's world - 'don't you ever tell me to go away in my own home ever again'. You were punished.
Can you imagine how this man would make your life, and the life of your child, one long punishment for daring to leave him? What kind of father her would be?
He would fight you for contact and he would get it, domestic violence or not, sadly.
You don't need to look far on here to find many stories from women who have gone through and continue to go through hell trying to protect and nurture children they ar eforced to see damaged and affected by co-parenting with violent, controlling, vicious men. No they don't put their children first. Yes they do treat their children badly. Yes they do realise just how much they have you by the balls when they have access to your children and they ruin lives and ruin childhoods.
You will never be free of his influence for the rest of your life, new relationships, other children notwithstanding.
I can see from your posts that you want a baby and it's a hard thing to say but please, think very very carefully.
