I am so sorry for you OP and your kids too. Your husband will moan like a bitch in 10-15 years when he is older (middle age or older,) and his kids don't want much to do with him (if anything.)
As I said on a thread the other day - sorry for copy and paste, but it is very apt for this thread too.
MANY men leave the vast majority of the wifework and childrearing to the women; including school plays, sports days, parents evenings, dental, doctors, optician, and nurse appointments, hobby groups, sports clubs, dance clubs, sleepovers, issues at school, dealing with other mothers in the neighbourhood or school, cooking for the family, looking after the kids when they're ill, helping them with homework, and taking them on daytrips, and to the park, and concerts, and plays, and suchlike...
Then these men wonder why, when the kids are grown (like 15+) they are closer to the mother than they are to them, and often choose to live with their mother than their father if they split.
Hopefully you can encourage your partner to start contributing more to the upbringing of his child, before HE ends up like this. Coz I have heard many complaints from some men, because the kids are MUCH closer to their mother (as young adults...)
They still love their father, but are much closer to their mother. Every time I hear this, I just think 'well maybe you should have contributed a bit more to the upbringing of your child(ren) then.'
Your husband sounds hideous though OP, and I would be surprised if your kids even want to KNOW him when they are older.
