Half is basically impossible. That’s not what people mean at all when they say split finances. It means that people retain their own personal money in some form instead of it fully being community property. I would consider having a joint account that’s only used for regular expenses to also be split finances if people have their own savings and investments.
The ratio of the split floats around for us, usually depending on income and desire to pay. The important part is that my money is mine and in my name. If I want to spend it on caviar or video games, good for me. If he wants to spend his on a new car, cool. If he wants money for that car he knows he can ask and probably get it, but then I get an opinion too.
