Is this a good or bad thing?

My ex recently said I’m misunderstood. I didn’t ask him to go into detail because i didn’t understand and didn’t really want to continue the conversation, but it’s been lingering on my mind what he could have meant by it. Im obviously not going to ask him because it was a few weeks ago and I don’t want to contact him just to rake up past conversations, especially as we’ve split up. But i just want to know, or have some kind of idea of whether it could be a good or bad thing, maybe i could then address it (if it’s bad) for future relationships. Any helpful opinions are welcome ladies
