I get zero attention from women lately

I have been born and raised in a relatively small city, (60k population). When I was younger 18-20 I used to have more communication with girls, through school, from socialising etc.

Nowadays ( I’m 23) I’m leaving in a much much larger city and I get zero girls. As much as I try to “date” or to find someone through social media doesn’t end well, when I’m out in a bar trying to communicate, doesn’t go as well as it used to be.

I decided to hit the gym, six months and still counting, and I believe because my self esteem has increased I have some more attention but nothing too crazy.

But genuinely I can’t find something I like. And to be honest it’s very hard to find anything at this point.

What can it be? Does anyone else have the same issue ? Any advice?
