To cut a long story short, I discovered back in March that DH had been cheating. He cut all contact with the OW, who is now travelling on the other side of the world with her partner, and is doing his best to make amends.
This morning I discovered her travelling blog in which her latest post is about working as a Nanny. It is very tempting to add a comment along the lines of "I don't think Mary Poppins shagged a married father of two."...
Should I....?
