Some guys might think that the girl is too many leagues above him, low self esteem etc, when the girl really likes him, so sits and waits and throws flirts at him, but he just gets even more depressed seeing other men openly flirt and engage with the girl, even to the point of going out with her.
The girl enjoys the company and the dates, but really wishes she was with the other chap she likes, but of course he just gets more depressed and feels inferior so never asks, as the years go by she just gives up and thinks that it will never happen, so picks one of the other lads who she thinks will be good for marriage, but deep down she likes the other boy and ends up becoming depressed that he never liked her enough to ask her out.
Anayway did I say you were annoying? NO, just the thought process!
Maybe we should go on a date a nice diner maybe and have a chat about it.
