Is ex deliberately hurting me post-breakup?

Broke up with him after I caught him lying, despite the fact that. I really did love him, and still do.

I broke up as respectfully as I could, focused on the actions rather than him personally. He and I have gone no contact, and I didn't see a need to block him before but now I am considering it. I feel like he is deliberately trying to hurt me.

He is posting on social media about places and restaurants that he knows I wanted to try, that he and I never did. I ran into him on two dating apps: the first had subtle digs at me. The second, he used a picture of us together. It's not even a good picture of him, but it's specifically the last picture we ever took together.

Why the hell is he being so cruel when I have tried my best to be civil, even after HE lied to ME?
