Last night, Susan and I got into an argument.  So is this simply a confession? No. I’d like for good to come out of it. Here are the cardinal relationship rules that I broke last night.  First, I broke our 9pm curfew on having serious discussions. We’re usually tired and cranky after that time so we shouldn’t talk about important topics. Last night, it was really late, about 11:30pm. Second, I broke the one issue rule: only talk about one issue at a time with your spouse. I let one small issue become many issues. Here are the rest of the rules I broke and What I Learned from a Fight with My Wife Last Night.
