I would have to agree. If you know that the marriage is over then the only thing to gain by “clearing the air” for either of you is bringing up more hurt feelings and anger. You can’t change any of it or make up for it.
For the sake of closure, forgive yourself if you did something that worked towards the demise of your marriage, forgive your spouse too. Realize that there were a lot of events that may have led you to this point and that it takes two to make a marriage work or fail. Grieve for the relationship if you need to and know that you have now learned what NOT to do.
“If you insist on holding onto an injustice or injury you are the one that continues to be hurt.”
Eventually, you may end up like I am. I was devistated at the time that we split up. But I’m no longer sad that that part of my life is over. Instead I’m grateful for what it was and what it taught me. Good luck to you.
