Having personal boundaries in all areas of life (emotional, physical, sexual, spiritual, etc) is one of the most difficult, but one of the most rewarding things you must learn to do. This does not mean you quickly cut people out of your life when they make mistakes. Don’t use boundaries as an excuse to hurt people. Having boundaries means you both kind and courageous at the same time. Allowing others to hurt you knowingly or unknowingly is not a kind thing to do. Gently and clearly let them know what hurts you. If it continues without effort to change and sincere apologies, it your right to put distance between you and that person. You are not being unchristian (Jesus had plenty of boundaries) or uncharitable by creating distance, you are protecting yourself and those you love. That isn’t unkindness, that’s heroic.
