Just tell him so he can be aware and learn. Maybe he would change? He is left wondering for no good reason. Ghosting is a self protection mechanism used by those who have poor communication skills. To answer your question -Ghosting is only appropriate if you are physically or mentally threatened. This does not qualify
You don’t owe him a second date, but at least saying hey our date last night don’t get me wrong I had a good time but there were just somet things that I think Make us no compatible and I think I’m going to have to end things, have a nice life. Idk that’s just what I would do. If a man makes it this far in life without learning to chew with his mouth closed I don’t think he’s going to change that. But maybe just tell him something like that instead of ghosting
