Good advice. Talking is important and a first step I recommend is making sure your on the same page. In other words the words your using mean the same thing to both of you
If you and your partner speak the same language and grew up in the same community or geographic area most people assume when they speak what they are saying means the same thing to both of them. My husband and I discovered that was not always true for us and the fact we were disagreeing was our first clue once we discovered the problem
An example of what I mean would be for him to say he had a bad dream and didn’t sleep well then to tell me he dreamt of fire. Fire in dreams was entering nightmare country for him and most people I know. I have never been frightened by fire in my dreams. Even when it surrounds me I am having a good time
There were many other things but this is what I remember most clearly and what did the most to keep our marriage peaceful with the talking never stopping until his Alzheimer’s shut him down to a very large degree
