Today, I release the devil I know in both him ("step-dad" stereotype personified) and my ex-wife. I hope that their mutual anger and unresolved pain can find resolution at some point in their lives. I no longer have to give him a centimeter in my heart.
When I get in a tough place I try and picture my kid's faces. In the moment I am feeling upset, I can send them a "How's it going, I love you" text. I can SnapChat a silly face.
