So I was gaming this girl all night long and I pretty much had it in the bag early in the night. I stayed a bit longer to dance with her and prep her up even more (still a newbie at this pua thing). I go to a small college so everyone knows each other. Anyway it was obvious that the girl and I were into each other to everyone at the party. While dancing she notices one of the dj's cd's on the floor and picks it up. The dj is my friend so I tell her I'll be back in a sec to give it to him. When I turn around some dude comes out of nowhere and starts grinding.

I know this guy as an acquaintance; so I talk to some other guys I know at the party who tell me what's up with your prize dancing this other guy. I was gaming another chick at the party so I trying to be rational beta and go for the other chick. I decided that I invested too much time into this chick and went up to the newly wed grinding couple and told her it was time to leave. The guy put his hands up in a submissive way like a oh snap (beta) and I went home and fucked her. Now how should I greet this guy the next time I see him lol? I kind of felt bad (once I again I am new to this PUA/Dominance thing).

You made her buying temperature high.

Then he came, willing to steal her from you.

Is it okay to go there and retake the girl? Is it okay to greet him the day after? Wasn't I too harsh to him when he wanted to fuck her?

Oh lord, it is not. You did okay. Just greet him anytime you want, but be aware of what he's done. Now you know he's a bitch.

You did well with pulling her back to you. He was the weak one when he let you walk away with her on your shoulder. If he's done that, he is not your friend. I never game my friends' targets.

By the way, good job with pulling her away. It willhappen to you many more times, so it's good you know how it feels when you defend your prize, you'll repeat that in future.
