You said you texted him once, what was your response to his ‘so excited’ comment? Is it possible it sounded unenthusiastic and he thought you weren’t interested? Also, texts aren’t totally foolproof, sometimes they just don’t go through and get lost in some void.

If it is ghosting, you need to step back and look at it without emotion or feelings. He’s a rude jerk! Count your blessings that at least he showed you what a dick he was BEFORE you met! How annoying would it be if you had met in person, liked him AND THEN he showed you his true colours?!
