We all reach a point when we must close the door on people and things whom are dragging us down and no longer serving our needs in a positive fashion.
Though, these endings are sad, closing the door enables us to minimize the damage to our overall well-being.
Earlier this year, I had to close the door on a future that was no longer applicable to me. It was painful, but at the same time the experience brought me to a higher understanding of myself and others.
I am now more cognizant of what my emotional needs are in a relationship. If I had allowed the door to stay open, then disrespect and resentment would have camped out it in my emotional living room. Those two would have taken turns making me feel worse about an already dysfunctional situation. Better just to close the door and step away from it.
