Background: AFC together
A year ago, one of my best friend gave me the Mystery Method book. So we were discussing and practising together. We had many failures in the beginning, but after a while we got better.

Meeting new people / opening sets
Since I was always the 'more social guy', I met more people and opened more sets, and he followed me. He had more problems to overcome his AA. Everytime I add someone on my FB, he added that person too. Actually he was following my steps. He waits till I have a conversation with someone, then he jumps in. He never initiates himself.

HB7
Lately I am gaming a girl who works at my gym, where my best friend and I work out. Since I opened several people there, and everytime when i am in a conversation, he jumped in. So my best friend knows this girl, i was gaming, too.

This girl, a good HB7, was sometimes very interested and sometimes not-responsive. So I rewarded her when she was responsive, and freezed her out when she was not responsive. Because my bestfriend was my wingman, I told him my tactiques and what the progress are. I also told him about her, what she told me.

But my bestfriend/wingman now, is gaming her with all the info i gave him. When i initiate the conversation with the HB7, he jumps in and invalidates my negs towards the girl. And he games her! So now two guys are gaming ONE girl.

Dilemma
So afterwards i asked him why he was gaming her, while I started the conversation.

He answered:
- he knows that HB7 too, so he also has the right to game her [he knows her because I opened the HB7, and he jumped in the conversation];
- since I was gaming her for several months already, without significant results, I could not claim her [i have to admit, that this is true]
- He is a PUA too, so he is not holding back for anyone

I answered;
- I told him that I was gaming this HB7, i gave him info about the girl (age, what she studies, etc.). He knows I was still gaming her.
- the fact that two guys gaming 1 girl at the same, is not going to work for both of us. And since I opened the set, it should be my set.

So my dilemma is actually;
Am i too narrow-minded, and be more confident about myself, and that my wingman should game her too?

Or is my friend/wingman becoming a selfish PUA, who ignores the rules of wingmanship, or the code of friends?

If he is wingman he shouldnt go after the girl you want, he should be helping not cockblocking eachother. Never seen Beautifull mind?

I would ditch that guy as my wingman. No friend of mine would do that shit.

Yup. Let him have this one and don't let him tie you down anymore, he'll make progress on his own time. Surround yourself with alphas, natural and otherwise, and you won't have problems like this. Your friends will have too many girls in their own lives to need yours. In fact, you'll often be catching hot girls off a friend's social circle.
