Geez, my brain got exhausted reading about this scenario!
My bad - it's just... I'm 35. At this age, I don't even try to analyze why a girl I want to get with is acting a certain way to where we don't hook up. I'm a "bottom line" kinda guy, so here it is:
She has NO agenda. She's not trying to build up emotional whatevers so you'll commit to her. Nor is she trying to sleep with you.
It doesn't really matter WHY she's doing it. What does matter, however, is that your brain is trying to justify these behaviors because your ego hates the idea that a girl this pretty would hang around you for this long and still NOT want to bang you.
I know. It sucks. We've all been there.
However, the end result of all her behaviors is the same, regardless of reason: that she's NOT hooking up with you.
Do you know how much women actually LIKE sex?? Much more than we do - that's why they're so selective of who they have it with. They know if they connect with a guy they don't want to be with yet the sex is mind-blowing, she could become addicted to a guy she knows isn't who she should be with.
This isn't to say that she's made this decision about you already. But, more likely than not she has, so she's not giving it up.
Again, women LOVE sex. And, if she wanted to have it with you, she would have done so by now.
