I like the income based share of expenses. If you make 75% of the total income, then pay 75% of the bills. Mortgage could probably be split 50/50. That's what a friend of mine does and they're both very happy.

Unfortunately, I can't convince my wife to contribute this way. I pay all the bills other than her car payment (when she has one), car maintenance, and gas. I also pay about $6k-8k of her self-employment tax. On top of that, for years she spent more on her hobby than I did on the mortgage. This has created some stress for me. Not only is she not contributing to bills, but I have to cover her taxes, and she's spending in a way that I never would.

So the risk becomes that if we do divorce, I'm totally screwed.it feels like the only way to control her spending is to keep the money separate. If you're not making enough to spend thousands a month on hobbies, then it becomes obvious that you can't do those.
