I believe that living with anger, creates an angry life. Showing the angry life to your kids is not the lesson you'd prefer to give them. Discharge your anger however you need to do it, but quit firing poison darts at your co-parent. You are liable to hit one of your kids instead.
Though I had no map for the road ahead, I did have my own core happiness and strength. And even though the future had suddenly appeared darker and more ominous I responded with laughter. The situation was not funny.
