Women are not turned on when you're more excited to be in a relationship with them than they are about you. They want to feel like they won by getting you. The way to show that is by being emotionally unavailable.
This means you could get close to her but it's not close enough. It's when she feels you like her but that she's not sure how much or how firm that is. The way to do this is to just never tell her how you feel about her.
Try your best to never tell her how much you feel ever but if you ever do accidentally show how much you like her, make the conscious effort to pull back. This way, she can have the evidence that goes against the evidence of you liking her. Simple as that.
Literally, make the effort to constantly throw her off. Be aware of what you do when you like a girl and what you do when you don't. Be very aware of how it feels different and your behavior.
Let's not go too far though. From time to time, you got to validate her and tell her you miss her. When you tell her that you miss her, do it only when she asks why you don't tell her that you miss her and why you're so busy because you're so unavailable. Only when asks you as to why you're not putting in the effort. Telling her you miss her rewards her chasing.
The key is to consistently keep her in that state.
