If my partner turned to me and said why don't you stop me, I'd have to ask him if that's what he really wants me to do, and if so I'd probably say okay then stop, and if he didn't stop I'd just laugh and say I guess you really don't want to stop, do you? If he really truly wanted to stop then he'd probably just stop and it wouldn't have much of anything to do with me and what I do.
