That's ridiculous @ZiggyNiko .
Why didn't he want your son to go to this nursery?
How much would his choice have been?
What's the difference in cost?
Not that it matters because of course the nursery fees and all the other children's expenses should not be down to you to pay.
I think him saying he won't pay because you chose the nursery is just a way of him avoiding that expense.
He really does sound like an awful controlling miserly man. Your life with him sounds pretty joyless. And he sounds like a pretty absent father too. Clearly he wanted you to have the second child to keep you away from financial independence, not because he loved being a dad.
You do need to get your ducks in a row, which will give you information, and options.
First step is to find any financial papers you can, including any that show where the house deposit money came from (you can request copies).
Take any such paperwork you find away with you.
Check online too if you can (although I appreciate that might be difficult if not impossible).
Even finding the names of his bank/pension/investment etc would be useful.
His money must be going somewhere - worst case it's wasted on gambling or drugs,but I wouldn't be surprised to find he's socked loads into his private pension and other investments.
Ask to have the earnings/expenses review before you go away, so that you can both do some thinking on it while you're away.
Write down what you pay for child-related costs every month, itemise it all.
I would suggest that when your DS starts school, the money you were paying for nursery fees should go into your pension instead. He really shouldn't argue against that, although he probably will.
When you come back from your trip use some of your savings to pay the costs of adding your name to the house deeds.
Once you have done that, and have the financial info you need, you can decide whether you want to stay with him or not.
Good luck, and I hope you enjoy your time with your parents.
