Why would a guy act serious and seem so interested in me for a date and he ends up ignoring/ghosting me?

It seemed like everything was going well we had some nice conversations prior and we were supposed to go on a date then yesterday he never texted me to hangout and opened my snap leaving me on read. What's up with dating nowdays.
