One of the most important things in a relationship is understanding. To understand someone we need to know how to listen to them. We also need to know how to show empathy. We also need to care about them and their feelings.

It also helps to learn what invalidation is. This is important because when we are invalidated we don't feel understood.

In any relationship there also needs to be a high level of mutual respect.

Because there will always be conflicts, a conflict resolution system is also important.
