All these inconveniences are incidents to love: reproaches, jealousies, quarrels, reconcilements, war, and then peace.

Friction is part of the arrangement rather than a fault in it. Reproach, jealousy, a quarrel, the making up afterwards: these turn up in nearly every close attachment, and treating each one as evidence that something is wrong adds a second problem to the first. Two people cannot be that involved with each other without occasionally colliding.

This describes ordinary trouble, not cruelty or fear, and those are a different matter entirely. For the ordinary sort, get better at the reconciling rather than at avoiding the quarrel. Be the one who comes back first this week, without requiring an admission before you do it.
