While my ex doesn't read my poetry, she knows there's no coming back from the way she tried to blame the divorce and everything around it on me to assuage her own feelings of guilt for abandoning her sick husband.
Everybody knew what had happened and my discretion was appreciated by her family and my/our friends. I got rid of my anger by writing poetry and a self-help manual using martial arts to overcome a divorce.
However, unlike most of you here, I couldn't 'ghost' my ex-wife or go incommunicado, because we have children together. Children who were 6 and 9 when she initiated the divorce. Children that we have to co-parent.
After nine months of hostilities my ex-wife asked me if we could talk, she had trouble sleeping and she had things on her mind.
I told her we could talk about the children, but that as far as the rest was concerned I had moved on and I was very happy and I hoped she would find happiness herself.
I heard later that she had taken my response quite hard, but her betrayal of her marital vows shouldn't be without dire consequences.
