It was a lot easier in the 50's when guys worked to get a girl to go out with him. but now it seems like if you want to see if they're really interested and don't JUMP at the chance to go out with them, they'll move on and find some girl who's easier.How do you play hard to get without the other person losing interest?
then don't get too hard to get. be yourself, make a good impression that makes him keeps chasing you. but if he went away and finds an easier girl, then maybe he's just trying to get back at you by making you jealous or he's just not for you. you wouldn't wanna be called easy would you?How do you play hard to get without the other person losing interest?
i think that in the very very beginning of a relationship there may be some 'playing' hard to get, but, after a while...yep, it is a dealbreaker when it goes on seemingly endlessly. it can be a deal breaker.
yes! times have changed and people aren't willing to put the effort in their relationships they should.... they would rather talk to the person who is ';putting out';
