Should he have told me he was done & going down stairs?

My boyfriend invited me on a trip to see his mom & we’re all about to go to the mall and he checked to see if i was getting ready & then went down stairs without telling me 💀like boy i was taking my time and was about to go in his room and didn’t see him there. it’s the little things that’s pissing me off but i love him.
