Negotiation and fairness is when both people agree on one thing and it's fair for the both of them. It is an approach to resolving conflicts peacefully, for finding common ground when the decision-makers have different viewpoints, or for pursuing your own goals in spite of those of the other participants.

 When you and your partner can express your wants and dislikes to one another and come to a fair agreement, that is the sign of a healthy relationship.

When one partner makes all the decisions and the other partner simply accepts them without discussion or negotiation, that situation is unhealthy.
