Sorry, I have no wise words to give. Just that you have my understanding for what it’s worth. I think the best thing might be to let them/the other person calm down for a bit, as forcing the issue with someone who is not prepared (or willing) to respond is a lost cause, and might actually make things worse. I am sorry. It hurts to be accused of something either unfounded and/or without just cause. But maybe with time, tolerance/open-mindedness from all parties, the misunderstanding could be resolved... with time. Just give them their space for the moment. Just my two cents.
