Congratulations!
My advice, get your financials sorted early. What I mean by that is you need to agree on what money is shared vs what money is your spending money.
The way my wife and I do it now is we each get $100 per week to do whatever we please, no questions asked. The rest goes into a joint account for paying bills and mortgage.
But it wasn't always that way. Before this arrangement we would regularly argue over money. This one simple change really made a big difference.
There's also a few other things that help a lot. Automate your bills out of an account that always has a few weeks income in it. Any additional money from bonuses or side businesses need to be split fairly. Doing forget to account for taxes.
Oh, and buy Bitcoin regularly, a happy marriage will follow.
