All, should I do anything to make amends in reference to that stupid, childish e-mail response I sent her? I feel like I should offer some sort of an apology. Thoughts?
IMO good manners are always in style.
"Wife, I behaved poorly yesterday. I don't believe you are a horrible person. I am sorry if I offended you."
Keep it short and simple. You are also modeling good behavior to her - leading. This is how adults act who care about each other. Now don't expect a nice response if you do it.
