When we fail to set boundaries and hold people accountable, we feel used and mistreated. This is why we sometimes attack who they are, which is far more hurtful than addressing a behavior or a choice. For our own sake, we need to understand that it’s dangerous to our relationships and our well-being to get mired in shame and blame, or to be full of self-righteous anger. It’s also impossible to practice compassion from a place of resentment. If we’re going to practice acceptance and compassion, we need boundaries and accountability.
