Hi, in response I understand what your going through but I believe that its human to be snappy from time to time but what I have done to for family is insist that we talk about the situation or whatever it is that is getting next to us but for the most part I find what helps us is giving one another time to alone. I think the answer to the problems is knowing what they are and being willing to work on them.
I have to say I make all except for 2 - I have been pretty good at using a positive tone with my wife. I would have to say the worst for me is #5, I tend to take her for granted.
