Glad you are both talking and making some progress. WTG!
Now that you are both aware of this kind of potential thing you can both take a new action when you converse. Maybe talk slower.
Maybe mirror? Before moving onward in the conversation repeat back in your own words
what you think the message was? To avoid misunderstandings and derailing off the tracks later?
Then when you arrive at whatever conclusion, could make it a habit to repeat back the mission to each other.
"Alright. We are in agreement then. I will do ____. You will do ____. Right? Are we good to go?"
Gives you both a chance to calibrate and make sure you are REALLY on the same page.
