I used to live under a young couple with a baby. I'd listen as she followed him from room to room upstairs, stomping, slamming things, throwing things, screaming. After about an hour, he'd eventually hit her, and everything would go quiet. An hour after that, they'd be out with the baby in the stroller, looking perfectly content with each other.
A man I know who has experience with men in abusive relationships would get his clients to answer a questionare. Things like, "after the violence, did you have sex?" "If so, how would you rate the sex?" 100% of men in reciprocally abusive relationships said "yes" to the first, and "scorching" to the second.
He also posited that the much-quoted cycle of violence--the build-up, the explosion, the honeymoon period--correlates with foreplay, orgasm and post-coital bliss.
Erin Pizzey called it "consensual violence", and said in the main, that was the type she'd see at her shelter. It is also the type that results in the most severe injuries in women, surprise surprise, likely because our "never EVER hit a woman" mentality has those men waiting until they completely lose control of their emotions before giving their women what they're demanding.
The DV in Sleeping with the Enemy is the most rare form out there, half as common as "matriarchal terrorism", and injuries are typically less severe. It's seriously foolish to treat all cases like the most rare type, and refuse to address women's instigation and participation in violence.
I don't really find too much in the article that strikes me as seriously ethically questionable. DV isn't pretty. Neither is the article.
