Disrespect is a significant root of the downfall of a relationship. It's good to master the art of discipline. Self-control, processing what is about to come out before it does because one disrespect might be the beginning of the ending of a relationship.
It's best to embrace silence when you are upset with your partner. Disrespect most times comes out of anger. Always remember that moment will way off but the action you have taking or took during that moment will hardly way off.
Some partners could let go of the disrespectful act you portrayed maybe once or twice, but there are some who would not permit it even once. Even though it doesn't escalate at that moment things might not go back to the same way it use to be.
Prevention is better than cure. Learn how to rule over your emotions. Do not let a moment destroy what you have put in so much effort to build.
