A friend of hers encouraged her to ask me for an open marriage. I said no. But this friend was also cheating on her husband with a married man of four kids.

She divorced her husband, sold the home to buy him out and moved elsewhere. It was her who told my then wife "it's not cheating if you tell him you're separated."

Last year, my ex wife invited her to my daughter's sweet 16 and lo and behold, she turned up with her exhusband who is now back with her.

My relative told me that my ex WW is now the only member of the "leave your husband behind club."
