This is so true. We need to love people when they make it hard to because we need the same thing in return. This kind of reminds me of that bible verse that instructs us to forgive others because we, ourselves, will need forgiveness.
There's a lot of psycho-babble out there about how no one can make you feel a way you don't want to feel. What a lie. Hurtful words have incredible power. They feed strongholds, they build walls, they break hearts.
Sometimes walking away has nothing to do with weakness, and everything to do with strength. We walk away not because we want others to realize our worth and value, but because we finally realize our OWN.
