Her marriage didn't fail because of this. It failed because she was...
"Trapped in a marriage where the sex was routine..."
Do you realize how intolerable that was? She had no choice but to go $crew strangers!"
Yeah, it’s a little difficult to maintain a marriage when both the husband and wife are narcissists. Seems to me the marriage was the project, not the wild oats.
Her marriage failed long before this. It failed because she wanted children, her husband didn't and went and got himself a vasectomy.
These are the "minor" details that really need to be hashed out before rings ever get slipped over fingers.
