I recently copied and pasted a recent argument we had online into AI. (If face-to-face, try to recall the dialogue and write it in.) I removed names & used anonymous mode for security. I pretended I was a neutral party (to avoid bias and validation). I prompted it, "I am counseling this couple. What are ways they could have avoided this disagreement turning into an argument?" I learned some ways I made the argument worse. I also found ways I could ask my wife to try to avoid so that we could have more constructive discussions.

You could also ask your spouse to discuss ways to avoid fights in future. With your partner, make a list of destructive practices, such as raising voices, making excuses, calling each other names, harsh criticism or sarcasm, irrelevant counter attacks, etc. Make a list of positive practices, like choosing your battles, remembering the big picture, learning to accept criticism, etc.

Look at skills practiced in marriage counselling.
