Hey stu. My W's reactions generally fall into the "atomic fireball" category. I used to let that control my actions ... in other words, I avoided bringing anything up that might set her off. Now, my attitude is more like, "her reaction is her problem" or "what's she going to do, cut me off?" or "I need to be able to look myself in the mirror, so I'm bring this subject up for my OWN good," or "just remember to duck" or "surely she won't do anything to me while I'm driving....EEEAYYYHHHH!!!!" or "what are you, a man or a mouse?"
Women generally appreciate assertive men. Exceptions to that rule do occur, unfortunately.
