So this girl goes to my dance class, but is from a different school. From our conversations, she is probably an alpha female as she is the leader of a prestigious school's dance squad. I go to an equally prestigous school, but aside from dance class, we don't really hang out. She's not the type to date an AMOG though. I've gotten the re-initiate covo ioi, and some other passives. Basically, she's comfortable with me but idk if she's into me yet. She maintains a really cool attitude at all times, and even suggested I remove my pants to stretch after dance when I forgot to bring shorts. Calibration is hard at this point-is she showing genuine signs of interest or is she just messing with me because she is alpha and a year older? On a side note, now that some rapport has been built, how can I use the fact that she is comfortable around me?

You should try to get some face time outside of school. Drop hints to her about this awesome party/concert/whatever event you are attending and tell her it would be cool if she could join. It's a "non-date", so she'll be less likely to get defensive about it. Plus, it would give her an opportunity to watch you in the company of your cool friends doing cool stuff. If things progress, separate her to another location, like a lounge or some place where you can work on comfort. Good luck!

Update: It was actually going pretty well until recently. I now have her number, but apparently she saw through some of the banter lines I was using. She then claims that she can tell when I'm not being "sincere". How can I rebuild this rapport?
