I know ghosting sucks but would you really feel better if he had broken up with you face to face? Our actions, even if ghosting someone, tell you everything you need to know. I'm sorry but you've been dumped and that's just how the game goes. Gotta kiss a lot of frogs before you find your prince. Shake it off and move on. But I'll just point something out-

I was planning to go on a date with a cute guy that progressed from grindr, to instagram, to a phone call. The phone call really made things feel like he was interested in me and I felt a connection to him.

If you met this guy in grindr and "felt a connection" after a phone call, I suspect he might not have been in the mood for romance. If he's on the hunt for dick and you start falling in love after a phone call, yeah, he's gonna bounce.
