Most Helpful Guy
Most Helpful Girl
usually i tell my girlfriends he is not worth your time. i mean there are other reasons like communication being down or etc but this is a smartphone generation. usually all messages and texts come by. what i mean is he is avoiding you. and most likely erased your number.
one of my girlfriends went through this similar situation and we found out unintentionally that he was married and was looking for a meaningless fling!!!
so he did disappear. but he's not interested in you :(
