I like the approach, but why not ask her for an immediate answer, yes or no? Be nice and give her 5 minutes to decide.
At least you can make other plans if she says no. Enjoy the TV show or head down to the local pub for a beer and game of darts.
I wouldn't sit and stew, or wait all evening to see what her response is. That is way too much control.

I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
