Hi Leeann, So sorry your hubby is a yeller!! My father was also a yeller my whole childhood. He mostly yelled at my Mother and she in turn, would go days, and I mean days, without saying one word to him. She was always good at giving him the silent treatment. So, Dad would always tell me to tell Mom this or that and in turn, Mom would tell me to tell Dad this or that. I always hated it and to this day, I hate yelling and I hate the silent treatment.
When I married, I didn't marry a yeller but I found out I married the silent treatment type. I kept telling my husband over the years, how much I hated it. He knew my Mom and Dad before they passed, so he knew each ones way of dealing with things and knew how I hated both ways. Eventually, a few years before my father passed, he did learn to control his temper and became a very docile man. In turn, my Mother quit her silent treatment and they had good years of marriage after that. My husband also finally stopped the silent treatment with me. If he got upset with me over anything, I would get the silent treatment and I never thought that was fair because most of the time, I never knew why he was giving me the silent treatment..
Tell your husband that it really isn't good for his health to yell like that. My father, although it was hereiditary, he also suffered for years with heart disease, heart attacks and surgeries because of it. The getting sooo excited and yelling so much was putting a big strain on his heart and blood pressure.
I wish you the best and I hope your husband will learn that yelling isn't the answer.
Good luck to you.

Linda
