My wife makes about 5-6x what I make

But I do make $200k/y

So what we do is that her money is hers and mine is mine

If she wants to spend her money on joint things like our house than that’s fine but I am clear with her whenever I won’t join those projects because I can’t afford it

It’s been working just fine

I know from friends though that it can be a issue if one of the partners has a income below a certain threshold
