It’s a push and pull thing. She likes the attention and is emotionally immature. It’s an exciting game for her and it all depends on if you want to play it or be a victim to it. Best advice is to push when she pulls. Basically play hard to get but leave bread crumbs like what she’s doing or just be mature and disengage entirely
Not all that relevant. This could be how she’d like to be perceived just understand that she’s playing a game with you and might not even be consciously aware of what she’s doing. She is likely doing whatever feels good/right in the moment which is why her actions seem inconsistent. She is impulsive and immature seemingly and you can work with that if you’d like. The main issue is you are thinking too much just understand that she is doing WHATEVER FEELS GOOD IN THE MOMENT with no second thought
