No relationship is both people playing the same position. Regardless of whether you pay 50/50 on bills or one pays everything, different people still have different strengths.
We are more "traditional" in our domestic roles than you'd think if you just knew me (I have a good career, I'm very independent, love DH to bits but I'm very much "the boss" at home). I am the better cook so I do that and the shopping that goes with it, I like the washing up (ten minutes with my music on makes it almost mindful), the laundry etc as I WFH most days. He prefers "tinkering" so he does the cars, the DIY, fixing, making, etc. He also works on site 5 days a week, so that's accounted for.
We share the childcare, outside of my non working days. Everything is covered by one of us, but neither of us "holds" more than half, on average. There are times I need to pick up more and times he does. We do that. Because we're a team and rather than only playing to our strengths, we do what is needed to keep the family ticking over.
You might prefer a "masculine provider", but I'm not entirely sure you know what that actually means. DH is very laid back, to the outsider it will look like I get my own way all the time. In reality, I get it most of the time, because he genuinely doesn't mind either way. If he does, he gets his way (or we have a discussion if I'm entirely against his way but that's rare). This doesn't mean he's not "masculine" or a "provider". He's both. I also "provide", it just looks different. Doesn't make me "masculine".
