I disagree. Just because you are the man and the perceived head of the household, doesn’t mean that you automatically should be responsible for paying most of the finance. Personally, I think that it is best to spit it 50/50 (if both parties make around the same). This is 2017. Most women make just as much if not more than most men. Back in the days many women were stay at home moms. Well that is no longer the case.
