What the...? Sounds a lot like my ex. He talks to me and enjoys my squirming too, and then makes me feel I'm the one at fault. And I did fall for it.

Don't contact him. Obviously he doesn't care enough to ask more and even blocked you! But I do think he is being human and making a mistake though. Nevertheless, you shouldn't put up with this sort of treatment. Ask him a question, ignored, when he asks you a question, you respond (and it wasn't even near mean, your response I mean) and he blocks you. What? Where is the logic here?

Ignore him. He shouldn't waste anymore of your time. Sorry if this sounds harsh, maybe your experience is mirroring mine right now and I'm feeling angry and hurt even though you are the one suffering.
