EDIT: *intEresting behaviour

So , I am going to ask for some opinions here. I am 17 y/o (soon to hit 18) and I am pretty popular in my school.

We have been to the mountains for 4 days( new year party), 25 mates ( all of us were 16-17 y/o)

The usual stuff, alcohol, weed and loud music. Everyone having fun, just good vibes. I go with the flow and have a good time as always, not getting drunk because I know if I am lucid, I can fuck my lovely girl friends.

Not being cocky here, I was the highest SMV there (shared with another good mate).

Not suprisingly, after a few minutes, the hottest girl from that chalet came and danced with me. Pretty sexual touching and all the rest. I knew it's on. She broke the dance after a while not saying anything, not giving any sign, and went upstairs. I followed her into her room and found her alone. There we chit-chat for a little bit and the she start saying that she doesn't like anymore her crush and that she liked me before. When I heard that I pulled her and start kissing hard. I get my clothes off,kiss her neck and so on. Things heat up. She scars my back, I caress her pussy while making out. All of a sudden she stops and says that we shouldn't do that because we are classmates and it will be awkard afterwards. She pushes me out of the room and wishes me good night.

The following days I didn't tried anything else with this girl for two reasons: I would have been seen as needy and she tried to 'pick up' another frinend which is kind of 'beta' and 'nice guy' (she has been trying this for some weeks).

I have to mention that this girl is popular, too.The usual hot girl stuff: attention from every single guy. She have been getting laid since her freshmen year from the senior year guys or even college guys. She often says that guys are jerk and so on.

Why does she became a 'nice girl' and orbit this guy ?Did she just want to show herself that she can 'have me' too?

She almost fucked me and she doesn't even hold hands or anything with this good guy? Is red pill different at that age?

Is she tired of this fuck and dump thing? LMR? I don't think so because she literally threw me away from her room. I didn't experience something like this before

I am not mad or anything, but I haven't been let with blue balls before.
