How We Stay in our Own Lane
When we argue with our mate we do so from our own point of view. This is how we are as individuals, trying to get people to see our side. When we get our feelings hurt some of us think about what was done to us, and then we lash out to the person that hurt us.
This reaction is common in relationships, but it hurts people. I have worked with many couples who are pretty much wired similarly. They both want to get the other person to hear how they were hurt. They are really good at being mad at the other person and trying to get their attention. Only when they are both doing this, they create a war between them.
