Verbal abuse can be fully as destructive as physical abuse. Most people, who practice verbal abuse, are suffering from low-self esteem. Very likely their parents verbally abused them. They are simply handling their anger in the same way their parents did. If you are married to a verbal abuser, you cannot change them, but you can influence them.
Here’s one approach: Say to the abuser. “I know you must be terribly angry to speak to me like that. I wish I could share your hurt, but I can’t hear you when you’re screaming. Next time, why don’t you write me a letter and tell me what you’re feeling. Then, maybe I can understand and be there for you.” Will they take your suggestion? I don’t know but it’s worth a try.
