I have been single for two months now, there is this guy whom I used to like but he was taken, now he is single too and he has been flirting with me for a week now and I am doing the same.. He asked me out but he didn't say that it is officially a date ! and now he is acting weired, we were chatting and all of a sudden he apologized saying I can't talk, I am in a real bad mood and went offline ! the guy is driving me crazy, sending opposite signals, how can I possibly know if he is really flirting or if he really likes me ! I kinda feel this bad mood is a result of his ex-gf am afraid he is still in love with her ?!! what can I do, really I need help !!!
