There's this guy that flirted with me at first but I acted distant a bit cause I didn't expect that from him all of a suddeb and after that he started talking to my bestfriend and is ignoring me to point that he says hello and goodbye to my friend but acts as if I don't exist also the other day when we entered the elevator he also came with my friend and I then asked her to drive her but sounded nervous when I looked at him and he was looking away
I usually am not this analytical about a situation but since I have a crush on him I really want to find out about this situation?
Is he interested in my friend and I should stay away from him?
