Some people think of interacting with people online (or not in person) is just play. Maybe they act like a stud and have an avatar that looks nothing like themselves. It's sad because they don't consider the feelings of the person they're interacting with. The fact he didn't end it after the first cancelled no show date says, to me, he was more interested in getting attention from you then considering you as a person. So sorry.

My sister did a lot of online dating and she set up parameters. She wouldn't continue messaging/talking to someone more than a few times if they didn't meet in person.

So many people on here have asked some really good questions about how invested you got in this guy before meeting in person, good stuff.
I used to have these sort of fantasy relationships where I was, on an emotional level, practically dating someone I hardly knew. It caused me a lot of heartache because I was always feeling rejected because they didn't bring the same feeling/investment/care to our interactions as I did. I've had some scary abusive relationships in the past and I was unconsciously scared to get involved so I focused on situations that would never really happen.
