Was I wrong for reaching out? Nothing happened between us so why is he being rude?

I congratulated this guy who I knew years ago. I congratulated him on getting married and hoped his family was well…

but looking back maybe I was wrong for reaching out because he left me on read and was not receptive to it… it was like he was playing mind games and I don’t understand because we never dated or anything
