I've been running through a few situations in my head and here one I can't solve,so you're talking to a girl a a guy comes up and says hello to her and starts talking now he's not a random they're friends how can you get him to leave without seeming like a dick.You can't use AMOG tactics because then you're mistreating her friend

You invite him in, if your into PUA at all my sure youve heard "i never do what anyone else does", it sets you apart from other guys who would just AMOG him out and tell him to go away. This makes it seem like your not there just to hit on her, and your not a jelouse guy who she'll regret. If he's there to long and in your way do something fun only two people can do, and right when shes happiest tell her you have to go and let her stay with her friend, then she'll realize how much better it was when you two were alone. BTW if she's paying more attention to him ITS A HINT, if your boring id want some friend to come save me too, if im telling a story on how i saved someone she'll pay attention to me, if im talking about the weather and hes talking about how he saved someone she'll watch him. dont give her a reason to ditch you and she woulnt

Be friendly to the guy and shake hands. State clear you're not competing with him. Chat, laugh and continue talking to the girl you like.

Only thing to do is make him your friend. If that is girlfriend, and you be friend him, chances are, he or she will have friends and they will hook you up. Happened to me.

This one girl I sarge, her boyfriend shows up. Be friend them both. Next thing you know, got invited to an after party with so many women. This is why I love social gaming. It has so much advantage or direct or sexual gaming.
