pretty much blew it.
Her roommate's boyfriend brought his roommates, and he started chatting her up during the show a bit, "what year are you in? how'd you meet your roommates?", etc, etc. Well she's showing some IOIs like facing her body towards him, eye contact, etc.
He number closed through her roommate as we're driving home. Kind of a pussy move, but she thought it was sweet and said he was cute and asked if he was single.
So we go back to the apartment, and then I call her out in a way and said to her "Remember when I used to make you laugh?" and she burst out laughing. "yes, I just remembered".
Well, after some more small talk, she started getting ready to sleep on the couch. I said to her "is this my queue to leave?" and she said "no you can stay there if you want" so I said "well maybe I'll come cuddle you in a bit" and she made a "ttssss" sound. So I thought maybe it was a shit test so I said "ya I'm pretty fucking gross" and she said "No, I didn't say that". Then I said to her "I'll be there in a minute, I have something to finish on my computer (faked typing for a minute). I walked over to her and gave her a really quick (2 second) scalp massage and she looked up and she said "Good night

". I was trying to use that to transition into the covers with her, but apparently she had decided she wasn't gonna have it. I thought to myself "fuck it" and just walked away. Maybe not the best move, but I guess the quick thinking comes with practice.
All I have left is shock and awe for tomorrow. I couldn't get up the nerve tonight, and didn't have the best opportunity. She's doing a paper tomorrow, but I think I'm going to sit down next to her and tell her it's time for a "makeout break", and hopefully escalate a bit from there.
Not likely to work, based on the signals she's sending me, but oh well. I have no time left, and I have nothing to lose.
