Sometimes I get caught up with thinking that it is my fault (because, hey, no one is perfect and I have undoubtedly messed up sometimes). She zeros in on those aspects even though hers are elephantine compared to mine (correct word?
). It is very frusterating and the only thing that cures this is time (lets her think and calm down).
I had a friend in elementary school whom I played soccer with. We called him train because sometimes he would act like a train (he was a bit heafty). He would zero in on a player who had the ball and barrel rush him, not stopping for anything. Sometimes I think about this when I make a decision that I know I want but will experience resistance with the missus. I don't think, I just do. ( try )
I don't know how much help this is when you are asking your wife to cooperate with you. But pick what you want and barrel rush it.
My wife also once told me that if I say I am going to do something and don't or am validating her irrationality, it is almost "training" her to think that it is ok and is conditioning her to do it again.
