So my gf and I just got back from a 5 day trip to Vegas. The trip was just me and her, so we pretty much spent every hour of the past 5 days together. Tonight, I told her I don’t want to sleep over her place as I want to just hang out by myself at my apartment  for the night. I enjoy my alone time to play video games, watch movies, etc. but she doesn’t see that as a valid reason to not want to sleep with her. Her reasoning is that we won’t be together the next couple days because my roommates (who are currently out of town) will be back tomorrow, and I’m going to want to hang out with them since I haven’t seen them in a while. AITA for not wanting to sleep with her?
