A friend of mine was the 'bit on the side' with her colleague for many years. They had a 'casual' on and off thing going for years in various hotel rooms around the world and he often told her of other flings he had had whilst away.
She has told me all this over the years.
He was married with two DC's. He eventually left his wife and started a 'proper' relationship with friend and they have subsequently married. She is now re-writing history to say that they had a brief fling, he felt so guilty and he ended it etc etc and he hated himself etc etc and it was only the once with her.
Ermmmmmm. I have known her for twelve years and she has now been married for three. He still works abroad a lot and she says she 'trusts him totally'.
I am not hoiking up my judgey pants or asking any other question than how can she trust him and would you?
