Its simple cat-string theory. You engage in a relationship with a girl, show her that you have feelings, then ignore her. She will wonder why you suddenly stopped talking to her, start question her own worth, then throwing everything that she has to keep you. Eventually shell start throwing herself at you sexually and you can get her to do pretty much anything you want with time and patience. Its a beautiful thing really.
All you chumps who are so quick to pick up the phone and tell your girl that shes beautiful and that she means the world to you. All you chumps who wonder why your girl walks all over you and cheats on you.
Try ignoring your lady. Women never shut the fuck anyways so theyll still be talking when you call them back.
