The problem is, that this is the internet and we do not know anything about either of you nor your relationship. Secondly you asked for advice about finances and we've more or less told you to dump him.
It may be the way you've written the post. On face value I have the same reservations as the others...he seems very dominant and you very submissive - no offence, might be just the way you wrote it. He is belittling your frugality. And he is a hurry to get you installed in a large house and have kids... once you have kids it is much more difficult to leave.
I would say if you are as on board with this marriage and having kids, as him, and you think you are both completely well suited in every other way, then talk to him , nay insist, on organising your finances separately, so that you can FI and he can keep working, if thats what you want. Jacob at ERE kept his finances separate and there's probably a few threads here on that...essentially agree on joint expenses that you both pay half of, and keep the rest separate. I personally would find separating finances kind of weird, but it seems to work for some. If you are going to get sucked into a huge house/mortgage that you don't want, well this needs to be negotiated. If he goes and gets that mortgage and huge house and then expects you to chip in half and you don't want such a big house... well thats a problem in my view. You can't make him become frugal....he may or may not change, so if you are going to couple, you need to start the marriage with an agreement that seems workable. If he refuses to negotiate, or compromise, or work out how you guys are going to manage this, then I think that's an answer for you.
