Could use some insight on what to do here (I'm in highschool). I was talking to a girl and she invited me to a gathering of we friends at her house. Get along with the group well and it works out great because I really need to branch out socially. Only problem is I'm not even really interested in the girl that got me invited, but one of her friends I am interested in. I think it's more important to establish myself in the group than get pussy, but i don't see a way to safely secure my spot.

My options as I see them-

1)Get with the girl that got me invited and have a short lived relationship( plates and such don't truly happen at my age ) but our breakup results in my removal from the group as I'm newer

2) Game the second girl which results in a lot of tension between them and me, which results in my removal from the group. Even if I were to get with the girl, our eventual breakup would probably remove me from the group

3) Tell first girl I'm not interested, which results in me not being invited anymore since there's no reason to anymore.

So I haven't yet established myself among them and I feel like I'm fucked no matter what. Any advice here guys?
