Friend problem, need your help!

Okay well his the deal, Friday night we had our year 12 formal this girl we talked heaps at the night and party hard. Saturday night we had a post formal party, we talked at the start drink'd and all, then I was drunk I then hooked up with a chick there in which the friend is good friends with. During the end of the party she completely ignored me, I felt so cut. Then the next day Monday school starts we seat in the same maths class, we didn';t say a word to each other plus when we see each other, we don't say hey. unlike before we talked like every maths lesson and said hey when we went past.

but the thing is she wanted me to go out with the person I hooked up with.
why she ignoring me? is she jealous ? and how to fix it? in maths move to a different seat? please help we were good friends and all I dont want to ruin it just because of one night.

hope you guys understand!
thanks in advance

 

Take the affirmative action and try talking to the friend. It shouldn't feel weird because you two talked before everything happened. We don't know her true feelings, only she does. Once you find out what's up, post an update.

 

Just ask her why she is ignoring you.

 

Girls say one thing but usually mean another. Honestly if she's pissed you hooked up with the other girl, she probably wanted you herself.
