Idk, tbf if I’m dating a girl and she just won’t stay at my house or have me stay over even after she gives me “a cookie” (also I have problems with sex in a relationship being some sort of pavlovian transaction in a strange attempt to train me, but…), I’m going to assume that she isn’t really that into me and is kinda just stringing me along until she finds someone “better,” so I’ll probably be out. Especially if she’s not upfront about the deadline so I’m just left to guess at the odd behavior. If it makes me a bad person that I don’t want to be treated that way again, so be it I guess.
