I've already seen some good pointers in the comments. My wife knows what triggers me and also knows that I can't control in at times no matter the situation, sad, angry, nervous, happy, etc. It just happens. The best thing I can say without repeating what another comment said is, no matter how frustrated my wife may get at me for something else or if we have an issue, she will NEVER use my stutter against me or try to say I am lying. And most importantly, she won't baby me BECAUSE I had a hard time talking through something. At times you may have step outside of your feelings and let the other finish without any reaction.
