Was I wrong for thanking him for his from way back now that he’s married? Why didn’t he respond?

I had reached out to a guy from years ago at a camp thanking him for being kind to me when others weren’t. I do think he had an interest in me and his mother asked my mother about carpooling.. but he listened when others didn’t, changed the page to my book when I was lost, he even complimented me.. but those gestures meant a lot at that time:

I had a cousin whom I confided in about him when we were teens.. anyway she followed him on facebook and they followed eachother on all platforms.. I was so naive to think they weren’t talking.. but it didn’t matter. I tried to follow him years later but he didn’t respond so I left it alone

Anyway I thought about him and my cousin mentioned him getting married. So a few days ago I reached out to him thanking him for his kindness, wishing him well on his union and saying that I hoped his mom and twin sister was doing well.. and he never responded..

was I wrong?
