Sounds like a bad plan
If you want to reject her to provoke a showdown you have to actually reject her not forget to go to bed on time. She's LD, if you don't show up it's unlikely to register as a rejection...
ya show up and turn the baseball game on the tv and watch it, and make her beg for it and make her try to seduce you. frustrate her. but don't give in, she'll love it.
good point there, if you don't show up it is not rejection.
