It sucks when it happens but I understand why people do it. Especially with things like Tinder where she's probably getting hundreds of responses.
Yeah she was the type to get spammed I could tell. Very materialistic / social media type. Worked in fashion etc. In a way, I was happy to have got as far as matching with her and getting her number. But clearly my "FB presence" didn't meet her vain standards. It would never have worked ultimately. Just would have been nice to get a polite message from her before a blocking.
