At times it is obvious when a girl is somewhat intimidated by you for whatever reason. She would usually look quite nervous, perhaps even skipping words or displaying a general hyper-awareness when you're around. I always fail to act on these. I just don't know how to progress it further, and whenever I tried I screwed it up.

Any ideas on how to deal with these situations?

For example, right now there is a girl who sees me in our sports club. I noticed she hangs around me all the time, acting all friendly and so forth. She is, for a lack of a better word, somewhat awestruck by me (don't ask me why) and generally really fidgety and nervous when around me. Then i discovered that she's been stalking my uni's social profile quite a lot (there is a way to find out who's looking at your social profile, but i guess she doesn't know that). She also mistakenly called me on messenger at 11pm i think she was looking through my FB profile. The next time we met I acted as if i knew nothing, she was clearly super nervous but I managed to diffuse it and talk about friendly stuff.

She still hangs around, makes a bee line for me whenever we meet... what next...
