I used to make ~2x my spouse. Now she makes ~2x me (her increased a bit and by choice mine decreased a lot). We have always treated it as "our" money not mine or hers. Scott Pape in Barefoot Investor says couples should use joint accounts we haven't done that but it may be the solution for you, I would recommend that you both read the book before making changes.

And for what it's worth, be grateful she is doing well. it is awesome and she deserves your admiration & appreciation for her achievements.
