It is not love that should be depicted as blind, but self-love.

Caring about someone tends to sharpen your sight rather than dull it; you notice their moods before they mention them. What actually blinds is the account you keep of yourself, which quietly upgrades your motives and files your worst moments under circumstance. Everyone runs that editor, and from the inside it never feels like editing.

When a conflict has an obvious villain and it is not you, slow down there. Ask what somebody who dislikes you would say about your part in it. You need not agree with the answer to learn from how easily it can be said.
