i dont understand why everytime i think something could happen between me and a guy nothing ever does...the guy i fell for is a jerk..he plays hot and cold with me constantly some days he will flirt like crazy other days he forgets im in the room...i will be friendly, smile and say hi and he replys back hi with barely any enthusiasm..and on other days he trys to make so much conversation....what sucks the most is i dont even think he really likes me but hes ALL i can ever think about..i can never get him out of my head...its a major crush ...i honestly dont know what to do.... this is the most frustrating feeling...and dont say "move on" or "find another guy" please i just need some advice?
