I don't know if I would describe it as putting her first but thing that I do to make sure DW feels happy, safe, cared for etc are:
I make sure the cupboards and freezer are always full because she grew up very poor and feels more secure knowing that there is food in. I also used to make lists of meals that can be made from these ingredients because I'm the cook and she didn't see meals if that makes sense, now she knows magic will just happen so I don't do the list.
I always do a deep clean on her last working day before annual leave so that she feels like the relaxation is starting straight away.
I do any messy / gross jobs, it's not even a discussion.
I do all of the driving and rarely say no to driving her anywhere, she can drive but was in a bad crash and really doesn't like to.
Things that she does for me:
All of the budgeting, bills etc because my brain really struggles to work that way.
Always backs me no matter what, still brags on me to her friends (they must be sick of hearing how amazing I am, even I roll my eyes).
Does the cleaning most of the time because although I could manage it I have a chronic pain condition and would probably be unable to walk afterwards.
Never complains if I want to change plans due to pain / not feeling up to something, we just change the plans and enjoy chilling together at home.
These aren't exhaustive lists but they are things that are unequal in our relationship because one of us is making an effort / allowances for the other and therefore there isn't any resentment about doing them.
I think the issue in the OP is more that there appears to be resentment, something isn't feeling balanced.
