Resolution should reduce the chance of repeating the conflict.

A resolution that leaves the mechanism intact is only a pause. Everyone feels better, nothing structural changed, and the same conflict returns in a month wearing different clothes. Feeling resolved and being resolved are not the same condition.

At the end of a difficult conversation, ask what would prevent this happening again. A rule, a check-in, a division of labour. Unromantic, and it is the difference between repairing something and simply putting it down.
