That really blows. And not even a single 'thank you'? Man... I'd feel pretty slighted if I was in your position, OP.

And tbh, I've thought of meeting some folks I've known online for a while now, but I've held off out of fear I may inadvertently end up like your "friend" there, since I'm somewhat shy/aloof myself. Still always remember to say 'thank you', tho'.

(That said, I'm really glad I've met most of my online friends/acquaintances at places like conventions, since there's lots of stuff to do)
