Dear single mom, I am not the enemy. I am also not in pursuit of you when I smile or ask you how your day is going. I understand divorce is a bitch. Single parenting is a bitch. And we move on.
When you ignore your kid's messages and voicemails you are giving them a very powerful message about their priority in your life. There is nothing you can say afterward, the exasperation has already taken place. This is never a happy response, "I don't know, I can't reach her and she's not responding."
