When one is not in a good mood one cannot think clearly .Hence what such a person says cannot be taken seriously. He or she does not mean what is said or done.

No

Depends. Sometimes, it's true. Sometimes, it's to hurt the other person, badly.

What Rosalie said.

sounds like she needs to eat some food and then she'll be fine

btw, she's probably bipolar

It means she's too immature or uninterested to be with you. This is the real her. Move on.

Usually not. I say things during sex that i don’t mean it’s just in the moment it seems like the right thing to say

Most people don't say that kind of thing just because they are upset.

I think you might be in the friendzone, in what circumstance does she say she doesn't mean them? If it is accompanied by her asking some favors from you like do stuff for her then we can conclude that you are indeed in the friendzone

If she says them on the same sentence like "I'm not inlove with you... I'm kidding!" then she is dropping some hints boi

It means she has some serious issues.

The swapping between being sweet and mean is abusive, manipulative behavior. It is meant to make you desire her more, or she has low esteem problems and doesn't want to be hurt. However, it's clear she is a narcissist and doesn't mind hurting you. It's your responsibility to recognize a relationship that does that, and protect yourself from it by not being in it.

Your best move would be to move away from her socially. None of this is going to end up in a good relationship, or make you feel any better about yourself. It's destructive, and since she is already old enough to have mentally matured, what that leaves is a physically beautiful girl with a toxic, ugly interior. When your soul is crushed, it doesn't matter what that toxic person looks like, and it never will.
