I have know this girl for about 7 month's we have been flirting on and off, talking for alot on and off, so we decided to tekst me the other day, and we startet talking again, suddenly she says. so will you talk to me next time you see me?, because she have been coming to my school to meet some friends of her's and i didnt talk to her back then, because i was waiting for her to come to me. she sounded really angry at me for not talking to her, she even said i didnt even look at her.

me and some friends have borrow a friends house for 5 days, where we will be going at it, drinking and having fun. so i invited her to that party and she said yes instantly.

but do you guys think she's into me?
should i try make a move at this party?

thx for reading this

As it sounds, she's into you. usually girls wont get upset if just some random guy doesnt talk to them, and as you mentioned, she said yes in an instant.
But it doesnt mean that you sealed the deal already, make sure she comes to the party, get the charmer in you out of his cage, Be the fun guy, drink with her, dance a bit(if there's music) and eventually isolate.
Just make sure the logistics allow all this to happen, and that you have where to go with her when you wanna be alone
