In fact, there are a ton of possible reasons having nothing to do with what you did. Usually, they don't really even know why they are acting the way they are. Ask your friend to be very honest with you and that you value you her friendship. If she still doesn't want to talk to you or is mean to you, then it may be time to find some new friends. Terrifichicks don't do this to each other.
Friendship is about mutual respect and having fun.
If either of those two are missing then it isn't a friendship. And although it may seem very hard for you to think about hanging out with someone new, it may be the best thing to do. He doesn't have a very nice personality, and he has a really big attitude. Mostly he doesn't really act like he even likes me as a friend. But that's only sometimes.
