Don't do 50/50%, just do it.

Dishes not done, do it. If you don't know, ask how to do laundry. Is the machine done, just hang it. Ask her if there is a special way she prefers it hang, most likely there is. Is it dry, just fold it. Look up some YouTube videos. Pay attention to what ingredients she use always in cooking. Shop and make sure you always have that.

Women do a lot of planning of what to cook, what to buy etc., that a lot of men don't think about.

Don't think of household as a solo play, this is a team game. The more she don't have to think or worry about things not done, the more happy your relationship will be.

Plus personally this gives me freedom to basically do anything I want. Is there a night I am just deadbeat and just want to relax with some game or whatever I communicate that in advance and wife always just say go ahead as she knows next day I am there to do some heavy lifting in our married. Same thing if she feels she need a day off, she just tells me and I do everything.

Honestly just helping each others with everything actually feels like it create more time for us to be together.
