@**Faylicia** That person is not only a jerk, but she sounds abusive too. I wouldn't be surprised if she also kept ignoring you to get you hooked on her more. This is how these people work. They give you a very little only for you to not lose complete interest, then take it back to make you wonder why they do it. So they can control you.
Her attitude is disgusting, jerks are not fun trust me. next time stay way from this type.
A kinda similar situation happened to me with the girl I liked, but instead of being rude, she was passive agressive and suddenly got a boyfriend and she was always with him in front of me. Now I'm over it and glad nothing happened between us, but this was the worst type. Because she is always really polite to people and then just ingores you out of nowhere only to make you feel like you did something wrong.
