I mean if he was the sole contributor to being late then NTA but you feeling the need to ask online over this v black and white thing, and then not responding to #1 leads me to believe you also played a part in which case no ones necessarily an AH you both just have shit time management
I would say, think back on how many times you’ve made him late for things before. If it’s a lot more, maybe relax a little bit. If you’re always on time for him, then I’d say your feelings are valid. But we’re all human, if he’s usually ready on time, I wouldn’t be too mad but make it known that it wasn’t cool.
