But this doesn't mean that you can just walk out on someone who is a pain in the butt. In some way you've contributed to the other person's struggle to control you, and you've got to take responsibility for your part in the tangle in order to gain the power to heal it. Otherwise you'll just walk into another version of it someplace else. Then you'll see what commitment is appropriate to make to your partner. We've been dense enough to think that loving God meant effacing yourself, and that loving your neighbor meant always putting others first - and feeling guilty if you got anything you wanted.
Love has nothing to do with martyrdom and nincompoopery.
Practice recognizing your personal worth. Be kind to, encourage, and challenge yourself. Without that, loving others and receiving their love will just dry up. As long as you think of love as a human emotion, you'll never learn to trust it. Human and emotion are both words that denote constant variety and unexpected change.
