Think of those times when you got angry and said things that you wished you had not said. Thriving couples have a great tool to head this off at the pass.
You have a contract with each other that either of you can call a unilateral ceasefire.
Letting your heartbeat fall back to 100 beats per minute will allow you to say things creatively and with care.
But you must follow a prescribed ritual to make this happen effectively or one partner may feel abandoned and resentful.
