Sorry, Cadet, dont necessarily agree with that blanket statement.
There is no one size fits all way to handle this. Different people, different sitches.
Sometimes it is necessary for the MLCer to have a dose of reality hit them from time to time.
No one relationship talk is going to make or break the situation. I am not talking about a long, drawn out relationship talk. And certainly not in the beginning of all this.
But, just because they have a stage of development they need to figure out, doesnt mean they shouldnt also understand where their spouse is at.
Fy's wife often brings up the relationship and he answers in a clear, concise, non pressuring way. Nothing wrong with that.
Every situation has to be weighed on its own and then the best way to handle it should be decided.
