Me (18M) and this girl, "Jane", met each other and she was blatantly into me from moment 1. She was touchy, flirty etc..., So I invited her and her friends to a party I am hosting next Friday, and she gladly accepted the invite. In the groupchat we have made, what is happening between me and Jane is brought up while I am at work. She is incredibly aggressive to questions such as "You and OP are definitely having a romantic phase" and "What's up with you and OP", writing stuff such as "nothing is happening" or "you don't know what you are talking about". This morning I text her saying "How is my girl doing?", And she quickly replies with "your girl babe I am not anyone's girl". I'm seeing her on Monday, I don't really know what this means. She also posted a private story talking about trying to convince herself to not like her crush.
