Normal is sharing assets because- well, when you're married they ARE shared assets!!
I think you need to come down very hard on this, or be prepared to walk now.
Yes, your savings are also your joint assets - as is your home. Quite simple: you either go on the deeds of that house, or you don't move. No equal sharing = no wife, no family, no baby. You are not a chattel. His financial sacrifices? Remind him that you're about to make the biggest investment of all, giving birth to a baby with him. You're putting on hold your career, pension, risking your health. The hugest thing you could give him which he could not do alone.
Maternity leave: simple. This is half his baby. The 'hit' for this is not yours to bear. It is awful beyond BELIEF that a good partner would need to be told this - it simply wasn't a topic for conversation in my home. 'How WE will manage during maternity' was the topic - how our JOINT incoming cash during that period could stretch. That's how good people think. I he doesn't think like this , you have a problem. It isn't about money, it's about whether you are a decent person who understands what a family should be, rather than a selfish cunt.
Seems he's the latter - patting himself on the back for having 'grabbed' it all - house, wife, baby, without outlaying a penny!! Haha! Oh - hang on. She wants to go on the deeds to the house? I'm going to have to support her on maternity leave? But - but - why should I? It's my money! Huge huge red flag.
I would tell him that you want things set out as follows:
- joint account for all monies earned, from both. During maternity, this pot will decrease while you BOTH take the financial hit for BOTH OF YOU HAVING A BABY.
- from this pot, all bills get paid, inc mortgage.
- after all bills, the remaining monies are split 50/50 into your two separate accounts.
- a portion could be sent into a separate savings account, on joint agreement.
House in both names.
If this is done, then you will be happy to put your savings into the savings account to give it a good start off. Needless to say, any savings/investments he has go the same way.
You might remind him that now you're married, this is basically what the situation is in reality anyway. You own the house, you don't actually need to be on the deeds - in fact, him refusing to put you on would simply make him look financially abusive in a divorce court.
Hopefully this is a blip revealing a childish selfish side you can work through, but if not, I would seriously advise you to think hard. No, you DON'T have to 'make it work' with a child - in fact, it's impossible to do so. All you 'make' is a damaged child.
