Hi im (19m), i live in a student residenci and there is this girl (21f), at the begining was all normal until we start talking more and i invited her on a date but she couldnt at the time because of school maybe later but she never say anything so i took it as a reyection.

One month later in a gathering with some friends i hit it of with one of her friends (19f), since then she is all the time passing by but didnt care until yesterday that i was in the gym (theres a big window so you know who is in there) and then she comes wich she usualy doesnt go and start jumping the rope in my face so i see her ass for 10 min and then i was done so i leave, i pass by 3min later and she was y there.

Maybe in Over thinking but need advise.
