I feel really, really sorry for you
I've RTFT & I just knew from the opening post where it was headed.
Of course he should have come back.
He shouldn't have gone! And yes, I know he didn't know the severity at that point but bloody hell, you stop & check on your wife, who has just fallen, regardless of everyone being in a rush.
Anyway, one step back, a 4 day stag leaving you with 3 small children is incredibly selfish.
This chimes with me sadly OP. My ex was exactly like this. I had just had my 3rd baby (he was 10 days old) & had a difficult delivery & was re-hospitalised. So I was really only home a few days. My other 2 children were 2 (& toilet training, child's insistence not mine!), and 4.
H was going on a stag. It never occurred to me to ask him if he would cancel. I did ask if he could go for one night less, he was outraged. To 'punish' me, he announced the night before he was going early the next morning, instead of the evening as planned. So a full day extra really.
He arrived back late on the final day. Hungover to hell & utterly useless. I spent so much of that weekend sobbing.
I'd no family support.
He's now an ex & I see his treatment of me so much more clearly.
I don't want to loosely bandy words about but he's not a nice guy OP. Everything he's done & lashing out at you when you ask him to come home. FGS he should be worried about you, not even the child-related elements.
Another PP said he 'despises' you. Of course we don't know from this distance. But mine did. And it was there in every action. It's a v real possibility.
I hope your DSis can help you & make you feel a bit better for now. 💐 for you x
