Silent treatment solves nothing.
For there to be a good relationship you need to talk things out.
I've learned that when she is angry it is best for me to keep quiet and let her say her piece and release her emotions, during that stage 1 word answers are best.
Once she had finished then sitting down and calmly speaking about it is my preferred way.
My wife has a rule for us, any silent treatment must end by her bedtime.
Silent treatment scenarios, Is it normal?
