It depends on what kind of relationship you want to have with them. It's important if the relationship was nasty and you don't want to take yourself back to that place because it could be really bad for you. I also think you get into a habit of like having repeated closure chats. You're never actually gonna get an answer. Like yeah. She even behavior is entirely irrational. There's like absolutely no explanation and coherent narrative that's going to explain why your relationship ended.
