I know this exact feeling. My gf moved to London UK (we were together in Canada for 5 years) and she slowly ghosted me day by day, one thing at a time it reduced and my anxiety built day by day. It stressed me out beyond belief and broke me down. 

If there's anything I can say here, it's to not see him again. Ignore his texts, block his number. Turn it all off. Someone who does that is the absolute worse in my opinion. They don't realize the mental impact that can have on a person and now you seem to be suffering in that position. Reconnecting with this person will only hurt even more. You definitely dodged a bullet as everyone else is saying so don't put yourself in a spot to be shot again if you can.

Ofc I say this but if you do end up talking, don't hate yourself for it. Just work harder to avoid him. 
Please please take care of yourself first! There are better guys out there!
