Ok, i think now you should drop the whole spat. Theoden is right, be the Superior Man, or you will be carrying a relatively minor argument into your future interactions.
Or more honestly, you are angry about the whole situation, you are angry with your wife, and that anger is coming out in the way you relate over these smaller issues.
This is exactly the way your wife is handling things right now. She blows up over little things because she is carrying around a lot of resentment, guilt, anger, confusion, etc. You need to be the one with godlike clarity, don't let her get to you. You have been here long enough to know she is CRAZY. Accept that and deal with her like you would your teenager.
