I made a joke when my boyfriend asked if he looked like Batman or not, and it backfired?

My boyfriend sent me snaps of his body and asked me if he looked good, and I said yes. He then asked me if he looked like Batman or not, and I jokingly said, don't push it haha. He got offended and said that I was calling him ugly to his face, which I was not. I genuinely thought he'd join in on the joke, but now he's so offended he won't talk to me. What do I do to get him to talk to me again?
