Well the first thing I'd be doing on Monday is calling a solicitor and finding out how to register an interest in the current house. You know, the one you're living in, which is a marital asset and which you'd be entitled to half of if you split, regardless of how much money you put into it? Yes. That house.
Then I'd be informing him that actually, if we're arguing so much, I don't think I want to move. No actually, it is my decision too - I think you'll find now I've registered my interest in this house, you, err, won't be able to sell it and use the funds to buy another one without my agreement...
And then I'd be telling him to trot off and look up the legal definition of marriage, and reminding him that no houses are being bought AT ALL without my name on the deeds. Married. Equal. Family.
He wants £10k, because so far you haven't contributed? Ok. Where's his record of exactly how much so far you have contributed? He doesn't have that either? No. Because it's supposed to be a partnership. Pulling together, a team, caring in kind. Which is why you weren't intending to be billing him, in full, for half the cost of a full-time nanny, live-in, plus cook, housekeeper, laundress and overnight double time nanny care for every single day of your maternity leave. It would cost him a lot more than 10k - hmm, perhaps you should? What with all this simply being about business transactions after all, yes?
And asking your dad for money. Crass, inappropriate and wrong. Ok, if he wanted to offer, fine. Ok, if your H had been thoughtful enough to reveal himself as a money-obsessed, tightfisted miserable little bean-counter before you married, he could have asked you then, and you'd have had the sense to tell him, presumably, that actually you didn't want to marry someone with that attitude to money and thanks but no thanks, you'll have a family with someone else. However, he didn't. You married him, and what does he now have... a loving wife, a baby on the way, and (if he can wake up and start seeing what's important in life) a happy family. Beyond price, really. Unless you are stupid enough to start putting a price on it, when you usually find that that's the point at which you start to lose it.
It sounds like you've married an arse. Don't give him £10k. You and your baby might need it. Tell him you'll be going on the deeds of the new house or you'll be keeping your savings in case you might need them to move very far away from him and his miserable outlook on life. And don't ask your Dad for a penny.
