scenario: it's either the end of a date or could possibly be a longer date depending on if the guy is going to make a move.

Now in the past The girl will give me a sign by leaning closer or leaning in. looking at my lips etc. This usually prompts me to make a move.

Are all girls the same way? Do some girls want something to happen but not give any of these signs. I'm asking because the last date that I ended the girl wasn't even facing me. and we just kept talking. it was getting late and I had to work in the morning. She gave me NO VISIBLE SIGNS she wanted anything to happen. So I ended it. the next few days she looked dissapointed and then asked me out for another hang out.

If you are a girl do you give signs to a guy. if it's the end of the date do you act stuck up but expect something to happen anyway? if so, how can I tell the girls who want something to happen compared to the ones that don't.
