When my husband had an affair with someone else I watched his eyes glaze over when we ate dinner together and I heard him singing to himself without me, and when he tended the garden it was not for me. He was courteous and polite; he enjoyed being at home, but in the fantasy of his home I was not the one who sat opposite him and laughed at his jokes. He didn't want to change anything; he liked his life. The only thing he wanted to change was me.
