It's like when you hook a fish. If you get a bite the worst thing you can do is pull in frantically because you don't know if the hook is set... Once you know, then you start reeling in.
For women, sex is the hook.... you are the fish. She is letting out the line to make sure you are hooked... she knows this by how you respond.
Depending on what the chick wants (because that is really all that matters) how you respond will dictate what she will do. If you start chasing like a crazy person, and she wants to lock you down, you will be bread crumbed... she will start seeing how much she can get away with... next thing you know, you will be harnessed as she parades you around in matching ugly holiday sweaters, showing you off. If she really isn't interested in getting you into a LTR, and you start chasing... well... you will get ghosted.
The important thing to know is a woman that is REALLY into you, will not do this. When this sort of thing happens, the chick has an interest level in you that is slightly above average. If you want to try and drive up her interest... well... you just follow her lead. Give her as much attention as she is giving you. Keep trying to make dates and see how she responds. If she is getting easier to deal with, her interest level is going up... if she is making things harder and harder... well... she is drifting off so you just let her go.
Regardless... if you over-react it will not turn out well... you will either get gelded of ghosted.
