When disagreements arise between a couple, both partners need to have the opportunity to be heard. Both people need to express their thoughts and feelings in an open and supportive environment.
The first person should speak as honestly as they can. The other should listen, then express to them what they heard, validating what they said and giving importance to their perspective. This should then be repeated for the other partner (Speaking and being validated).
Both individuals should get their time to speak, followed by some validation, then finally it can be decided if they agree with each other or not. If they agree as a result of this exercise, great. This is what we all strive for, agreement and resolution, while getting our own needs met. If not, they must agree to disagree and move on. Disagreement is to be anticipated and is a part of any relationship.
But, if both people simply have their perspective validated by the other, real understanding can occur and they can both feel heard. Either way, this exercise will result in a positive outcome. As long as the dialogue is peaceful and calm. As long as adequate space and respect are provided to both members of the relationship.
