The gentleman I'm dating and I have discussed this. I do make more (not substantially but I'm a senior in our career where he's a junior so ... ) and he's so introverted that he makes my introverted self look almost extroverted. So yeah, we've talked about proper roles and I flat out asked him if it would make him uncomfortable if we got married if I made more than him. I think a lot of this can be worked out with good communication between partners, and finding the right balance for the duo in question. In my case, he is much stronger with finances and his walk with the Lord than I am, so I gladly follow his lead there. I am tomboyishly handy with saws and stuff, and can repair a lot of minor household or car issues, so I tend to take the lead there. (PS: no, we do not live together) ... so ... yeah ... communicate ...
