Husband cheating feeling?

Ok. before i start, I have NO proof my husband is cheating at all, so i feel horrible for even having the thought but hear me out. My husband is a pilot, he spends many days of the week in a hotel room 100’s of miles away. The other day I was on tik tok and saw a video about how all pilots are cheaters. I’ve seen many videos about this and my husband and I always laugh at them are joke abo it it. So i sent the video to him as a joke and said “Wow are you cheating on me” as a joke like we have done before. He was sitting right next to me and usually he would laugh and joke about it, but this time he got SO weird. He started getting super fidgety and was saying this like “i would never in a billion years do that, only the worst people on earth would do that…” and was going on and on and kept asking me why i would ask that and how he could be better so i wouldn’t ever doubt him. I was sooo confused because I wasn’t being serious at all and I kept telling him it was a joke and I’m sorry. Then he started crying saying he doesn’t know how anyone could do that to their family. My husband is amaizng, but now i’m worried. I confronted him the next day, saying his reaction really worried me and he got annoyed. idk what to do.
