Interesting choice of topic. It's never to late to learn about ways of resolving confict situations. After all - until day we die we will face such a times and challenging moments.
I focus on this point, since many families can remain distant and angry for a long time because pride, anger, resentment prevails over love and union
It's especially difficult when someone is using 'silent treatment' as a tool of punishment. Wouldn't you agree?
In my opinion (as a man) first step is to ensure that both (you and your partner) people will calm down and only discuss topic once emotions are under control :)
