My ex blocked me, should I block him back?

He blocked me from Facebook messenger, Instagram, and my number after spending 2 months texting me and trying to win me back (he ended our relationship), I rejected relationships until I saw a change in him, but agreed to be friends, our friendship quickly turned into him asking to be with me again, I told him to ask me when he next sees me and I will say yes (he lives an hour away) however I posted a picture with my guy friend and he seemed to assume I was sleeping with him, called me a snake and blocked me from everything without letting me explain. I attempted contact with no response from a different account.

When we broke up he told me he always looks on my social media and thinks about me, the only thing he didn't block me from was Facebook (only blocked on their messenger app, deleted me from Facebook) so I can only hope or guess he still looks at my profile. I know it sounds game playing but I did nothing wrong, he was the one playing games while trying to win me back, I just feel like if I block him maybe it would trigger a reaction out of him or at least help me have closure.
