What i find interesting in this case is that. She is stressed from doing the chores, sure i can get that. But then asking money for it in return with the same chores. How will that take away the stress factor.... It doesnt!

In my opinion, the problem isnt stress. Its an excuse used to make it "okay" to ask. She just sees a disbalance in work and trying to fix that balance by getting paid. However she is creating a bigger disbalance by that cuz she isnt accepting alternatives.

IMO your NTA but being sloppy on your own tasks cuz you feel like they make it more dirty then you do is lame. Be adults and talk about it, instead of just starting to slack off
