As psychologist Dr. Henry Cloud put it, you'd always get a combination of two things: "what you create and what you allow."
Rid yourself of negative, unhealthy, life-damaging "tolerating." Within you, your self. In your relationships. In your environment.
A lack of boundaries invites a lack of respect.
Take a firm stand. Put healthy boundaries. Care about what you create. Respect yourself.
What you allow is what will continue.
