You changed their mind. You won.
Wasn’t that the point of the argument, or was the point for someone to shower you with congratulations?
Take the victory. You know what happened, and if the other person doesn’t want to acknowledge it, you can’t control that, so just remember what kind of person they are and move on.
I understand completely. I’m the same way. Just gotta let that shit go. It’s only as important as you want it to be.
