playing hard to get

ever wonder why when one isn't  interested in a guy he is always calling, but once one actually becomes interested in him he becomes ambivalent and barely calls? i don't wonder . i know why . when someone is chasing after me they never have to evaluate whether or not they are truly interested in me because it is still a fantasy. once i become interested then it becomes a reality. then he actually has time to obsess about his actual feelings now that it could be a reality. this is why guys like it when women play hard to get (and vice versa). reality is much tougher  to fall head first into than mere possibility.
