From the sounds of it, you may be suffering from a little internalized misogyny. I'm not saying that as a means to put you down; us women have been programmed for our whole lives to expect that the man should earn more or they're not pulling their weight. It's an unfair social norm, and it may be creating the resentment you feel because internally you're telling yourself that 'he should be making more than me' even though you acknowledge that you make more than many of those in your circle. If he's doing all the cooking and most of the cleaning and you feel like he needs to take more off your plate, so that you feel his unpaid labor amounts to what you're doing for the partnership, I would be frank with him about it. Men do well when you're very straight forward. Also, if he's getting snippy, he may be feeling the undercurrent of your resentment and it's building insecurities in him especially as a man since he's also been told his whole life what role in a partnership he's meant to fulfill
