It is.
Personally, I couldn't care less how much money I'm earning and how much money my husband is earning. Relatively speaking, I do make more money than he does; I'm earning a little less with my part-time job than he does with his full-time job. But he enjoys his job a lot and as long as we manage to pay all of our bills and still have some money left to do/buy some nice stuff every now and then, I'm all peachy.
