Excellent question why in my case when I get angry I apply the law of silence to my partner and I wonder if it is a behavior of mine or learned because I remember that my mother did it with my father and my sister with her partner, I think that writing everything down would improve the relationship because we would express everything that deep down we think and to avoid more arguments we usually keep silent.
The silent treatment doesn't seem to help anyone, does it? Maybe problems just fester.
