I talk to a girl casually, and I'm pretty smooth naturally. Then the girl gets really into me and is always putting full effort forward, texting me, wanting to hang out, etc. Then when they stop needing me, I start needing them. With every relationship I suddenly find myself being super invested, even when I try not to be. I do the same routine with every girl.

Get invested, start second guessing everything I say, freaking out to myself over little things, and the girls just put in no more effort.

What's going on? How do these tables keep getting turned, even when I try and make a conscious effort for them not to? How do I turn this around and get the girls BACK on the chase? Helpful, thought out answers will be appreciated.
