Guy cancels, blocks, now I feel shitty

Last night I was chatting with a guy on Grindr and it seemed like we were both on the same page regarding kinky sex. He was gagging for it, so was I, so we agreed to meet Friday. I was really excited about the prospect of finding a guy into the same stuff as me, then today I find out he's blocked me. I know this because I 'favourited' him in the chat but he isn't appearing in my favourites section, but I still found him on my friend's phone. Now I just feel really fucking crap. I understand cold feet but this is just really shitty treatment and it makes me feel really unattractive.
