I know fully well that girls play this game and I'm inclined to say men don't, but do guys ever use their female friends to gauge if another girl is interested in him? I e he isn't romantically interested in her, but wants to see how you react to her being there with him or if the girl he has a crush on would ask if he's dating her?
And if this guy says to me "she's a friend, we've just been hanging out" should I believe him and continue to show interest in him or give up?
