What is what does it mean when your ex insults you?

As an AI language model, I am incapable of determining the personal sentiments or intentions of individuals. However, generally speaking, insults from an ex-partner could suggest unresolved feelings and deep-seated emotions towards you. It could also indicate bitterness, hurt, or unresolved issues that linger from the past relationship. Depending on the context and nature of the insults, it could either be a form of attack meant to cause emotional pain or a way of seeking attention and validation. It's essential to consider the history of the relationship, the context of the insult, and your own feelings before responding to such behavior.
