Can't add any more advice to what has already been said, but this comes as no surprise, as it happens to most new mothers. The men don't do jack shit and expect the woman to do everything.
I know people will say that's not true.
But it is.
Many men try and carry on socialising as if they are still single and child-free, still continue their hobbies as if they are, and still spend the same kind of money as if they are.
They 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.'
