when I met my wife we were both pretty much on the same level, I made more than she did but that didn't bother me. We both had our own places and after a year decided to get married and buy a house. Everything, in the beginning, used to be split right down the middle, after a few years I just told her to make joint accounts and take out whatever is needed, just don't mess with the savings.
I don't trip off finances too much, as long as everything is paid on time and we have a stocked kitchen, I honestly don't pay attention to the accounts. My wife isn't high maintenance so I never worry about her spending money on dumb shit. I never argue over money it's one of the rules I took into my marriage, the other rule I live by is, never to argue or interfere with the other person's family or family's issues, unless it's directly affecting you.
because of these 2 rules I've been able to stay married for almost 24 years.
nothing is perfect we have our issues (nothing major) but nothing worth fighting over, arguing, and fighting over material stuff is a waste of energy to me, none of it matters when you die, so live accordingly.
