Reflection is the Best Medicine

Good relationship advice from Dr Oz's wife:

Because dealing with conflict is a large part of any long-term relationship [I agree], you need to know how to air your differences productively. Too often an argument devolves into proving you're right—and as I've learned, being right is overrated. One way to tell if you're resolving your disputes in a civilized manner is to record your argument, and then play it back later. Did you fight fair, or did you come off like the Wicked Witch of the West? I once saw a video of a family vacation that captured a fight Mehmet and I were having in the background. I was so horrified by my venomous tone, I quickly erased the tape—but seeing that fight is still having a positive impact on our relationship.

Even more, if you know the fight is on film, you'll probably play nicer.
