Perfect timing, happened to me the same recently during a date.
So she basically comes up with the bull**** about just leaving a meaningful story so she doesnt "feel ready" to get intimate...of course she feels ready to date, tell me about her life, wasting my time and have fun according to her terms.
Needless to say no physical contact allowed while hearing the more creative excuses for that, she doesnt feel its time yet (yeah it takes years to let someone grab your hand while you move in the crowd).
What I did was basically withdrawing not my attention but my initiative, I was just listening at her and give detailed answers, smiling when she was smiling and so on but at the same time I stop putting any effort to make the conversation interesting, no more physical moves and no more personal talkings, just basically being passive in terms of topic, it wasnt the butthurt silent or a punishment cause she wasnt putting it out.
I just slowly and gradually withdraw commitment and energy, let her pay her drinks, didnt make any more plan for the night but just asking her what she wanted, when she said that it was late, I told her that if she wanted to go home I would have called a taxi which I did.
Told her it was nice meeting her with a big smile, then left when the taxi was at the traffic light.
This choice didnt come out of sympathy or tolerance but out of a cold reasoning, I may happen to meet this girl randomly or we may have acquaitances in common and it surely pays more to be "the guy with which didnt work but was ok" rather than be "that creep which acted butthurt cause he aint getting it".
So as a general suggestion I would say just stop being proactive, stop putting an effort and gradually withdraw what you have put on it, she will get it but she wont be sure about it.
