Preface: I haven't ever had a girlfriend, and I have no interest in one, until I'm fully confident in being able to assert myself constantly in the wake of shit-tests etc.

That said, I have been starting to do calisthenics for the past 2 or 3 months now, and I while I haven't really gained much weight, I have started to get more muscular and confident.

Anyways, onto the meat of the question:

There is a girl at my school who, a few months ago, started what I suspected was fake flirting. I didn't much care for it, because I knew I was of low SMV and ergo realized she was trying, and failing to lead me on. The situation has persisted , with me completely ignoring her attempts, and they increased in frequency after I began working out, although that may be imagined or rationalized. The (potentially fake) flirting culminated about 3 weeks ago, when, while I was waiting at a printer, she came up from behind and practically hugged me from behind, and felt up my abs. Again, I didn't really react, politely told her to let go of me, and printed out my IT work.

My 2 best friends know about it and they think that the best option is to pretend to go along with it. I personally do not care about this situation as I leave the school in less than 2 months anyway. I also hypothesized to myself that I may have accidentally been running DHV without noticing it. Thoughts?
