Many times I've met a girl in a bar, got talking to her, we kissed, I got her number, kept talking, decent rapport, then she goes back to her friends/I go back to my friends.

Then I text her the next day, and..... nothing. Or maybe a bit of texting back and forward that eventually dies out.

It seems to mostly happen with the youngest, hottest girls.

What's going on here?

Is it a lack of attraction? I would think that if she was willing to kiss me then there was enough attraction to take it further if I got everything else right?

Is it their age? Often 10 years plus younger than me, but I look younger than I am and I lie about my age...

Is it a lack of rapport/connection? Sometimes my conversation can be a bit flat/awkward.

Ok I've given very limited information here, but in your experience, what do you think is the most likely explanation? Thanks!
