Am I the only one who gets pissed & shuts down completely when someone continuously for years accuses you of doing something horrible, but you did not do?...

I am so over it. The little slick comments, the always having to bring it up in every situation. Ugh... then the "anger shows guilt" I've been told. BUT the anger comes from being pissed of being accused of something that never happened for years.
