I don't think it's right to ask her or bother with such questions. I have girlfriends who over time have become close to people they couldn't stand before. At first I was angry and did not understand, I accepted it as hypocritical, but I realized that life is colorful. Sometimes, when you give a chance to people who are unpleasant to you, it turns out that you have a lot in common and you change your mind. I personally got along with the whole flow during the first year at university, but the second year things changed and I found the ones we really fit in with as a way of thinking. I haven't fought with the others, but I'm looking for my people. Try to be a little more individual, for the moment you are attached to this friend and you are guided by her - when to go to lectures and the like. If you don't want to be late, go up the hall alone. It's not scary to be alone, in most cases it is not even for long. And don't be a pessimist compared to other colleagues, you have to be a great team, because one day you will work together. It should not be like a school at the university, strange intrigues should develop and there should be a division into groups. It is clear that you will not fit in with everyone, but it is good to give a chance to others and not accept them as necessarily bad.

You have no reason because she is just a social person and you are no different from everyone else in her eyes.
