I'd hesitate to say someone is "weird" if they do something financial differently than you or Rocco do... :)

While I enjoy reading your (very different) take on career and finances, and was equally intrigued reading Rocco's (at least until he blocked me - I guess he didn't appreciate my commenting that I disagreed with him so much), from my side of the table it seems that it's your experience and Rocco's that are further from the mainstream than mine. Not saying this is an objective fact, just that it's my perception based on reading your Medium stories.

I happened to write recently about three different ways couples share finances (https://themakingofamillionaire.com/3-ways-couples-manage-money-pros-cons-tweaks-peace-d713a7a3bfba), and my conclusion is that how (or whether) you merge finances with your spouse (or life partner) depends critically on the specifics of your situation.

What worked for me in my 20s when I married my ex-wife would not work at all for my wife and I. What works for us now would not have made sense to our 20-something selves. And if something that used to work for me would no longer work now, how much more true would it be when comparing between different couples.

Having said all that, the reason I think sharing finances with your life partner makes more sense than not is that you would presumably not want a situation where one of you can afford a luxurious lifestyle and the other can't afford a cup of coffee, and if one of you stops earning or earns far less than the other, that may well be the result of not sharing your finances in any way.
