He slams doors, breaks things, and yells so loud. I'm embarrassed because my neighbors for sure have heard him screaming so loud at me, but none of them are JWs. Then he goes on to give me silent treatment for days.
I am very sorry to hear of your family problems DY.
You probably already know this but the behavior your describing is meant to be used as a tool to control you (or others in your household). Sometimes it ends there but with others the behavior escalates if they have not gained the measure of control they are looking for.
I don't walk in your shoes so only you know how bad it is.
Is he the type of person that you could ask him to get counselling for his control issues? Likely he will not get adequate counselling from the JWs because many don't even have higher education let alone a degree in psychology or psychiatry, but more importanly, they may not want to address through self analysis his "control" issues as it is the cornerstone of their recruitment and membership structure.
