Check out her advice below:
Letter to a friend:
You are divorced. Your ex-husband is not being kind or considerate, but you can't harp on it because it steals the energy that should be given to your potential and power. At the end of the day, your survival is at risk, and you complaining about what he is not doing and what he should be doing does not change your circumstances. We have to use these circumstances to analyze what we need to do different, how do we need to strengthen, and how we need to be more. You are strong and capable, and now you have been put in a position where you must use your capabilities to change your circumstances without your ex's help or kindness.
In the ideal world, the circumstances in which you and your children are facing are unacceptable, but the most painful realization I have had about this life is that we are not entitled to anyone's kindness or consideration. THAT, is a painful truth.
Stay focused and keep it moving.
