How often do you fight with your SO? What are the fights like?

Me and my wife hate fighting. We tend to both swallow our hurts, and see if things will get better. This, of course, was not good. Even so, when we now bring up issues of pain, it’s not easy, but we don’t raise our voices, and we sure don’t hit. At most, we wander around with a sullen air about us, until the other person explains, or cools off.
