So in the past I used to go to chat websites and chat with strangers but mostly girls.

I was not in a good shape back then so whenever I sent a photo to a girl she turned me down

Except for that time where I got lucky with this girl

She even agreed to give me her Snapchat

We talked for a while then never really talked again until recently where I started to send her snaps from time to time, however she doesn't respond neither does she block or something like other girls do

What should I do ?
