Most couples have arguments during their relationship.
Some are heated discussions, provoked by actions that trigger deep anger, hurt, or other strong emotions. I dread having such times of upheaval in our relationship. Yet it's often during those troublesome periods that I find out things I never realized before about myself and my partner. For instance, my SO becomes extremely upset that I have been late one too many times, and I discover though the tears and screaming that they had a terrifying childhood experience once when their parents were late picking them up. An explosion over sexual struggles reveals that I was once raped, and had been too ashamed to tell them about it.
