Stage 4: Re-Engage
Re-Engage with the other person first clarifying your goals (Stage 1: Motivation to Change). Make sure both of you have the same goal: to resolve your differences while maintaining a relationship with each other. Both of you have to trust that the other is not going to try to dominate over the other (WIN-LOSE) and that both of you are willing to take the risk of truly expressing yourself to the other (not practice the LOSE-WIN approach).
Reconcile your differences maintaining reciprocal, accurate, and balanced perspective-taking:
Reciprocal: Take turns being the "expresser" and the "listener"
Accurate: The "listener" should paraphrase what the expresser has said and check for accuracy by asking "Do I have it right?"
Balance: Switch roles only after the expresser feels sufficiently understood and is ready to move on.
Note: this may take some time, so make sure you have the right time and place to do this. If things get too heated, go back a step to the "Disengage" stage. If you feel frustrated, go back the the "Motivation to Change" stage. If things get worse, seek professional help.
