He refuses. Ffs.
Leave him with the baby for the weekend in entirety and fuck off somewhere else.
You need to get that sort of sheer stupidity sorted out now.
Adults change nappies, wipe up sick and vomit, and look after their children.
If they don't, they shouldn't have shagged you and got you up the duff in the first place.
He is a father.
Tell him to act like one, and leave him with the baby until they understand they each other.
What a prize load of cock. And you, op, are buying into it.
That's if you haven't just popped on to wind up the wimmin.
Fathers change nappies. And they feed babies in the night too. And they are just as capable of it as the mother, with the exception that she has had to express the milk in the first place.
Just because he has a penis doesn't mean it stops him parenting.
You need to tell him to shape up, now.
And you need to tell him to fuck off for a vasectomy if he thinks he's impregnating you again, unless he starts accepting some bog standard ordinary parenting.
Unless you have time travelled from 1952. Obv.
Doesn't change nappies. Ffs.
