"Sometimes choices are made in the name of forgiveness while what is occurring isn't forgiveness at all. It is important not to confuse being forgiving with denying your own feelings, needs, and desires. Forgiving doesn't mean being passive and staying in a job or a relationship that clearly doesn't work for you or is abusive. It is important that you are clear about your boundaries. What is acceptable for you? If you are willing to allow unacceptable behavior again and again in the name of 'forgiveness,' you are more than likely using 'forgiveness' as an excuse not to take responsibility for taking care of yourself or as a way to avoid making changes."
- Robin Casarjian, Forgiveness: A Bold Choice For A Peaceful Heart

"Forgive a wife-slammer if you can. But you don't have to live with him. Forgive a husband who is abusing your children if you can. But only after you kick him out of the house. And if you can't get him out, get help. It's available. In the meantime, don't let him near the kids, and don't let anyone tell you that if you forgive him it means you have to stay with him. [There's an important difference between forgiving a person and tolerating their bad behavior.]"

"Use, do not abuse... neither abstinence nor excess ever renders man happy."
