After a couple of months I had to end it – and it was after I had made this decision that my husband found out.

He discovered messages on my phone and so I sat him down and poured the whole sorry tale out to him, feeling I was stamping on his heart with every word. I spent a lonely Christmas at my mother's house with nothing to do but wonder how I had got myself into this situation. I started therapy, and learned just how dysfunctional my life had been, and so little wonder I kept making new problems for myself.
I began writing everything down, to help make sense of it, first for myself, then for others.
