Just finished the Isabel Gilles memoir, "It Happens Every Day," which is her memoir of being an LBS. It is a wonderful, authentic read, like listening to your best friend, but it is heartbreaking. In fact, it dredged up a lot of pain I thought I had calmed and put aside. Its an especially compelling read for me, as my own divorce approaches.
Her late 30-something husband left her and their two small boys for a colleague after seven years of marriage. I don't know if it was MLC; Isabel was actually his second wife. He had left his first wife while she was pregnant. Isabel did not stand. She does not address the idea in her book. Her H divorced very, very quickly (3 mos) and then married OW and had a baby with her. Isabel has remarried herself. I am now reading her sequel, "A Year and Six Seconds," about how she found peace and love again. It's also very good. I also read some press interviews she did, in which she says she is now friends with OW. But I find this almost super-human.
Isabel Gillies books are far more emotionally honest than a similar divorce memoir I read, "Falling Apart in One Piece," by Stacy Morrison. Her story sounds much more like MLC, but I feel that she glosses over a lot of the relationship issues. Not as validating and inspiring as the Gillies books.
Everything will work out ok in the end. If it doesn't, it's not the end.
