i think we're missing part of the story details, but all i see is you pushing, pushing, pushing, and no pulling (?). You've had various opportunities to K-close and not taking them was probably not good.
Inability to pull the trigger, is seen as a weakness and its dangerous ground that could lead to loss of interest REAL fast, so there must be other really solid aspects to your game that keeps her coming back. Fix this and you'll be unstoppable!

Now on to a real example...
Mind you, I'm still quite new at this so i still make many mistakes, but anyway, the girl (HB7) was in our circle of friends. One of the first girls I ran "game" on, by the way. I had met her a few times, always tons of IOIs....
Long story short, I CF'd well, isolated well and built rapport well but missed a couple of good Kiss close opportunities. Anyway on the day-2 I finally k-closed and later that night laid her and although she put on a strong feminine exterior at first, when she was writhing naked underneath me in the shadow of the blankets she was putty in my hands, gentle, sweet, and tender. A delicious lay... but the part that helped me grow in my game was a convo I had with her later the next day when hanging with a group...
I said as a joke, "I don't remember much from last night. I hope you didnt take advantage of me" and gave her a sly wink followed by a little kino. She smiled in a way that I knew memories of last night's bliss flashed through her pretty blonde head. She said, "well you did have to get a couple of drinks in you before you could kiss me" AND BANG IT HIT ME! I should have k-closed earlier!!! I thought back to several opportunities when I was just afraid, and that fear blinded me to the realization that she was ready....To this day, I'm 99% sure I could have F-closed on NIGHT #1 if i had just PULLED THE TRIGGER. DO IT! DO IT! DO IT!
Say to yourself, "when I get X number of IOIs within Y number of minutes, I'm gonna kiss her no matter what." Then count the IOIs and when you hit your target, BANG! Success is almost guaranteed. Once you do it a few times, you'll lose the fear and always be able to just PULL THAT TRIGGER!
Well if you made it to the end of this post, hope it helped. Moral: Ignore Fear of rejection and just pull the trigger.
