Suppose a girl gives lots of attention, dancing close to you, and, because you step back (push and PULL) is literally removing parts of her outfit so you'll notice her, while lots of times bumping into you or even grinding you (say she is in front of you) you ignore her. Now suppose you notice that she's "actually" with a guy there. Wtf. So what do you do in this case? Pretend he doesn't exist or is a platonic friend to her? Pretend not to notice him and just reciprocate, grind back on her if she's into it, play hot and cold etc? Now what if he's like, "dude hands off she's mine" (in words or action) or for example tells you to beat it or points you to go dance somewhere else?

How do you handle these situations?
