Can't post this in general section

. Basically i taught my friend a little bit of the game over this past summer, by introducing him to The Attraction Code by Vin di Carlo, and since then i feel like he has become a lot better equiped to handle female interaction (not sayin he was terrible at it but he had a lot to work on)
Now he likes to "call" girls, which i dont mind because to be honest im not trying to sleep with every single hot girl we know, but i also feel like he shouldnt be allowed to call every single girl. The problem is, is that in most of these interactions he has introduced me to said girl.
Anyway the question..... We are all at a party and a girl "hes got in the bag" starts coming over to me tryin to chat me up and he instantly has to come over and try to get her attention i let it go, why would i care im havin a blast with my friends i havent seen in awhile. Later that night he basically tries to amog me by ignoring me right in front of that girl when its clear he can see me and hear me, when all im askin is where is the beer i had paid for haha. He later tells me he was just drunk and i was pissin him off askin him where the beer was? ---which to me sounds like bull shit....that takes half a second to answer especailly when i paid for part of it
Am i overassesing the situation or is he tryin 2 dlv me in this social interaction. And if so how should i respond to these dlvs, he obviously feels threatened while i dont even have any intention to steal his girls just because they chat me up.
The best solution i can come up with to the problem is to stay away from him for awhile, but its kinda hard when we have the same friends and our houses are a street apart (college campus)
