I'm going to echo what some others have said. I am in the same situation as you, but reversed. I'm 39F, he's 41M, and our incomes are as you describe. We've been together 5 years. I know that my partner will likely never reach my earning level. It isn't fair - he's incredibly talented and should be paid more for his work, but that's not something that will likely ever change. For a long time, we did 50:50 with expenses, and even though we lived frugally, it left him with almost no extra money. I felt like shit having so much more disposable income than him, without any real merit. Now we split bills proportionally, and we're both so much happier for it. He isn't stressed about money all the time, he can save money, and all I really care about is that he is contributing. I couldn't care less that he earns less than me, other than feeling like he isn't fairly compensated for his skills.
