Avoid people who mess with your head. Avoid people who intentionally and repeatedly do and say things that they know upset you. Avoid people who expect you to prioritize them but refuse to prioritize you. Avoid people who can’t and won’t apologize sincerely. Avoid. Avoid.

I see it all perfectly; there are two possible situations — one can either do this or that. My honest opinion and my friendly advice is this: do it or do not do it — you will regret both.
—  Soren Kierkegaard, Either/Or
Love is a decision, it is a judgment, it is a promise. If love were only a feeling, there would be no basis for the promise to love each other forever. A feeling comes and it may go. How can I judge that it will stay forever, when my act does not involve judgment and decision.
