So university just recently started

So the other day after getting out of a class , I saw a couple people i knew a bit from high school. One being , a guy that had class in a couple minutes. the other being this hot girl in knew a bit from high school ( just from her coming over to my place for gatherings and through some friends )

So , she asked me what my schedule was like right now . I told her i had an an hour and a half wait until the next class. she was like oh really , i also have some time right now . wanna chill ??
I automatically started to think to myself*wow ..wasn't expecting that * so i go with her and follow her to the very back of the library . im thinking damn im going to have to keep the conversation going for an hour?!.
So i keep the conversation going , not saying it was the most fun convo ever but i kept it going no awkward pauses or anything.
next thing we know some other girl who we both dont know jumped into the convo.

the new girl kinda pissed me off because it kinda ruined my game because the new girl and the girl i was gaming got into a good convo. and she wasn't really my type and i could tell she wasn't really feeling me.so i tried to keep up in the convo but it was hard. next thing you know it was time to go to class so i left

so just yesterday i saw the girl who asked me to chill passing by on campus. she was with some asian guy and we both saw each other but nothing was said and she seemed to give me a bit of a disappointed look..

what should i do the next time i see her?

what really pisses me off was that i was about to find a way to get her number and then the other girl jumped in.. so really i took nothing out of it .

first of all the girl who interupted should be able to tell that you 2 are into each other and she should but out. I think the girl u wanted held the conversation with the interupt to be polite.

what I would have done was isolated the target again. "sry but we have go to....(insert place here)." and whisk her away to some other private location, it does not matter where just as long as you 2 are alone.

She might be dissapointed because you did not step and do that. but i think you still have a shot at this one. next time you see her. escalate and isolate quickly, and be aggressive. you should be fine.

You should have been kino escalating as soon as she invited you to chill. "Alright, I can, but I'm exhausted, you'll have to carry me" then put your arm around her and slump your weight onto her. This is my biggest routine for initiating kino when I realize I haven't been. It jump starts you into a good position.

How good is your conversation game? I recommend The Power of Now for anyone having trouble with that aspect. You need to be completely focused on what she's saying.

When the friend came in, there are a few things you'd need to do. As soon as she came in, introduce yourself. Shake her hand, be ready to charm her a little bit. After a minute, say "We actually have to go, it was great meeting you!"

When you felt a little out of the loop, you could have waited for a comfortable break in the conversation, touched your target somehow and said "Hey do you still remember [random mutual friend]?" and created a conversation that the new girl had to be removed from, by lack of knowledge. She'd hopefully feel uncomfortable and leave then. This last part is harder to come up with on the spot though, I'm not sure that I would have.
