I learned this lesson the hard way a long time ago. There was this girl was a seeing and everything was going well, until I started nagging her all the time. Eventually she went into the arms of someone else, but as luck would have it we wound up dating again, only this time I tried something different.

I realized people, or her at least, weren't walking towards me because I have this strong gravitational pull, she came to me because everyone else was constantly repulsing her to someone. To get a girl to want to come to you every time, you need to be the person who doesn't put pressure on her so the pressure other people exert pushes her into your circle.
