Insecure spouse

Ok, I’m literally so annoyed right now. I was at the heliport with my spouse & son, there was a car parked beside me & right in the area where people board the chopper & get off. I was staring off at some guys wind pants blowing in the wind (he was old) & then my spouse says “I know who you’re looking at” I was taken back I was like “what that guy?”

I then realized he was talking about the guy in the car, I wasn’t even looking at him.. I literally only have eyes for my spouse 🙄 now he’s pouting & mad. He slammed the car door & shit. What should I do? Lol
