If somebody is intentionally rude or mean to you, you explain they are being rude, and they continue, are you allowed to speak lashon Harah about them to someone close?
For example, you are being bullied and called names by someone who you’ve warned about their behavior, are you allowed to speak negatively about that person?
If so, what are the parameters of it? Sources (preferably from the Chofetz Chaim), are always appreciated.
