I forgot to say this in my original post, the logic is simple:
Most woman have a ranked list of guys they are seeing. There is the number one they want and back up options they keep around in case number one doesn't work out. If you're number one, than things are easy and straightforward. She's going to meet up with you whenever you ask, she's going to hit you up by herself and she is not going to curve you when you make a move. If you're not number one, things are more complicated. She will keep you around but how far she will let you go, how much time she will spend with you and how often she will hit you up depends on how high you are ranked on her list. She will spend as much time and energy on you as is necessary to keep you around and interested until she finds out if things are going to work out with number one. Depending on her moral believes she might sleep with you, but she will not commit. If she get's her number one, she will go cold on you, unless she is one of those girls who thrive on male attention, then she will keep teasing you, because she loves to be pursued. If number one chooses somebody else or fukks up (although you really have to put effort into fukking up if you're number one) you will move up the list.
Of course there are exceptions to the rule, but from my experience, this is how it normally works. And another thing that my experience taught me is that you do not want to stick around if you're not number one, because it leads to frustration more often than not.
