Why is he acting weird?

After a year of getting to know this guy … we had sex.. I kept telling him I didn’t want to be ghosted … I ask him if I can suck his dick… he said not today and how he’s not in the mood … how his family is coming over. He won’t have time to chill with me. I told him enjoy :) and the next day I got no text message nothing from him … did I do something wrong by telling him I didn’t want to be ghosted?
