You are not a child. You are a functioning adult. You are not required to do 1/2 of all chores and needs, are you? You are required to  participate with more than your wallet. And my guess is that you aren't paying your wife to take care of the kids/baby and do the housework when you aren't home. You are paying by working. But you don't work 24/7. Why would you expect your wife to do the cooking and the cleaning and the raising and all the other household responsibilities 24/7? That doesn't seem very fair at all. You work 40 or so hours a week to have a home and family. But you want your wife to work, at least on call, 168 hours a week for the same reward? Participate. Don't diminish yourself into being the wallet. Be the Husband and Father and House mate and Room Mate and Partner. You really can.                              

When I was recovering from childbirth my husband helped me with everything. not just with the kids but with cleaning. Once I was recovered we went back to life as usual. I always did all the housework, cooking, etc myself. But he always helped with the kids, not just so I could have time to do what needed to be done, but to bond with his children

If you feel you can not pitch in with the housework you can always hire a maid to come in and help your wife with the housework.

Get her off her lazy butt. Do not give in.

Say "your duty is cleaning the house mine is bringing in money".

Welcome to the gynocracy. It's been this way for decades now. Marriage is a raw deal - especially for men. Do yourself a favor and leave this woman as soon as possible. It's not worth it.
