We've both found our niches. It used to be that I would do most of the housework while he took care of the children. It got a little frustrating, especially since I worked about twice as much as he did. But now as they grow older and more self-sufficient, things are equivalent more often then not. I cook, he cleans. I do the laundry, he does the ironing, etc. He takes care of his vehicle, I take care of mine. He takes care of the finances. I take care of the backyard. He takes care of the social niceties with others and so on.
However, it is not difficult to notice that he is the more assertive partner and is the breadwinner. Up to this point, he has earned significantly more than I do. While I do provide input, I let him make most of the decisions regarding big money spending. However, that will change in the next couple of years as I finish my training years. In the next 5 years or so, I will quickly out earn him. I sometimes wonder how he will take to a reversal of roles. Probably not well. People already joke about it and he laughs it off. I hope he keeps that up.
