Inb4 why do you have beta friends?

Okay I'm a junior at a major university in a major city in America.

I also smoke cigarettes.

Inb4 you shouldn't be smoking cigarettes.

Okay so there's this one spot where everybody smokes just off campus. It's in one of the high traffic areas so there's always chicks to talk to.

I'm friends with all of the regulars, and we're kind of one big social group of friends who hang out there all the time.

So a hb8 comes by and lights up, my friend initially plays wingman and doesn't let me use his lighter, so I go over and ask for hers. She goes to light me up and I grab her hand to help windshield to immediately break the physical contact barrier. She starts talking to me immediately so I didn't even need to start up conversation. Turns out we went to same high school and live a mile away from each other.

So all is going according to plan when the rest of the smokers who were too afraid to start talking to her come over and turn it into a group conversation. I'm not even kidding like 5 of them. And they all start trying to showboat and apply their beta game because since I was talking to her now they had a reason to try to talk to her.

She sticks around for a bit but you can tell she didn't want this to happen.

I don't even know what to do. So I just abandoned ship.

After a while she gets up to leave and turns to the group but only looking at me says bye and smiles and bites her lip and walks away.

I'll see her again so I'm not too worried, but how do I handle situations like this? I just felt off going with the whole "let's get out of here" or moving for a number or something because of how quickly the betas swarmed in. I couldn't build enough rapport.

What do in the future guys?

Inb4 this is why you don't have beta friends.

Maybe that's the best answer but maybe there's something else I'm missing.
