She’s prob bored and wondering why you haven’t suggested progressing things.
Not necessarily - yet anyway. As he says, she may well be intrigued and even interested; no doubt she has been inundated by guys messaging her and offering £££ for sex straightaway and here is a guy who is not rushing to get into her pants, but taking her out and showing an interest in her.
However, it should also be said, some of these girls are just curious ie they just want free lunch/drinks and spend time with an intelligent older man rather than a dull, selfish and poor boy their own age - but at the same time have no intention of going to bed with them.
You may therefore just be wasting your time and money (your call if you don't mind that) so I agree that after a few dates it's probably time to move things along a bit and start gradually introducing sex into general conversation and (at different points of the conversation, of course) trying to find out about what she is looking for ie cash or gifts.
"Whatever you want" may not be a bluff, so it may be worth asking if she has a figure in mind or she is happy leaving it you, leaving something for her at the end of a meet.
