Lucy Crocker 2.0 is a fun, interesting look at a 15 year marriage that has gone down the tubes. Both partners cheat on each other. One because he is bored and unhappy. The other because he did and she is stressed and unhappy.
There are some thoughtful insights into marriage and people. There are two crazy fourteen year old boys. There’s the blond tantric masseuse. The liar lumberjack, stealer of minks. It’s a good read.
Caveat: I do not think sex with anyone other than your spouse is right. I do not think that just because one partner cheated the other partner should cheat. The book is not good because the two partners’ cheated but despite that.
