OMG, yes, you pull that laundry out of the basket!
So what, go grocery shopping!!! And only for what you and son want and need! She gives you a request, you do not get it! She can handle it. She chooses to engage in an affair, you are no longer a husband to her.
Dead serious about, "you can do whatever you choose with MON,WED, FRI, ect, I can do whatever I want TUE, THURS, SAT, and we alternate sunday night" I would even tell her this is how it will be when you guys aren't living under the same roof, so she better get used to it.
Don't take this crap anymore. Don't be a cuckold.
Women dig men who have respect for themselves. But really, you should do this for yourself.
