Points where sidebar level TRP knowledge can be applied are marked with bold numbers.

I was in the process of plating a girl I've known for a bit, we had a couple of fun nights in the fall, and although I failed at LMR (1. wasn't nearly as persistent as TRP would advice) she kept coming back for more and would always text me about something meaningless after she was back home from my place.

We both got busy and didn't see for a month or two, and only in passing over holidays. When we got back to school, I went to her house and started initiating, but she threw a mini-fit about me moving a chair (2. shit test in hindsight, my mistake expecting everything to go as smooth as before), I stopped and her mood visibly changed (3. probably wanted me to pass the shit test and show aggression, was frustrated when I didn't deliver), we went on to have a shit talk about the holidays. After this some mutual friends came over to say hi and what I kept getting from her was not the usual shit tests, but just plain attitude and blunt comments on anything I'd say, even if it wasn't to her. Next day I tried to make plans for some private time sans friends, got a shit response. I've completely withdrawn attention since and making sure the next time we meet is in an intimate setting.

(Aside from "next", god damn it is cold for walking to parties in Illinois right now) I think the only path here is to be more physically/sexually assertive and persistent next time we meet than on any previous occasion, and not let it show that there ever was a setback, but I'm interested in comments from people who know better.
