i became friends with a girl in college . i was jealous of the men she dated , especially as she told me she would have dated me if we were n't friends . thats unfortunate . sometimes , people do n't know how to make a move and are waiting for you to make a move . yeah sorry i did n't hit on you immediately . i wish she would have just never metioned any interest in me . thats a good point . now you are always going to wonder 'what if ' ?
The unrequited romantic interest and the perceived missed opportunity caused the jealousy.
