A lot like your situation the tables have turned - my wife has made partner and now making 2x my tech salary.

Since before we were married we've each made a relative contribution to a joint bank acct and it's worked fine. (e.g. we both put 70% of our income in one pot). I like this approach because it's a balance of 'whomever can afford more, pays more', but also it allows for individual reward for someone working his/her butt off (e.g. if someone gets a huge bonus). I see it has a good hybrid approach.

For years, I was putting in more income as the higher earner and now the tables have turned. :)
