Bringing up old problems will just exacerbate the intensity of the upset.

Additionally, it will probably send the current problem to the back as you end up discussing all the previous problems too.

Plus, your spouse will be hurt that you still haven’t let go of past grievances.

Instead of:
-“You always are losing your keys. Remember last time….”
-“Yeah, you’re sorry. Just like you were last time. Yeah.”
-“You keep doing this.”
Just stay focused on the present issue.
