I'm going to yell at my wife to seek mental help and to stop storming off like a child
Why do you think she needs help?
Because my wife is short tempered
You should behave in a more understanding way when it comes to your spouse. If your wife is going through a hard time, you are expected to be there for her and support her through it.
But if I don't yell at her and make her cry, she'll storm off.
I think when you yell at her it has the effect opposite of what you said. If you have a disagreement you can talk with her like an adult try to be calm if you can.
