Haven't met, I cancelled our first date when he stood me up that night. I've asked him twice if he has a girlfriend while mentioning his strange behaviour and he told me he doesn't. I kinda believed him because he seems super inexperienced with women? But I can't know for sure and I don't have another explanation

I completely agree, it's also the reason I think it was dumb of me to agree to keep talking. Somehow I hoped I would get the spark back of what I felt before his behaviour started to bother me more.
