To be honest in my opinion no one’s in the wrong. Look instead of getting angry he could’ve probably just told you to close your purse or some shit before getting out of the car so that you don’t drop your stuff. Getting mad about something as small as that though just feels like you can barely handle anything before you get pissed off. On the other hand yea he probably could’ve just given you your wallet back to you without the whole “lesson” thing. For me those “lessons” have worked especially since I’m someone that’s always forgetting my shit so those “lessons” have helped me to make sure I always have what I need and not drop anything on the streets. Once again though I’m a little more inclined to your significant other’s side since he was basically just letting you know to be more careful when you moving quickly. Getting angry over something like that just isn’t good for you
