UK: Why are so many men becoming victims of domestic violence?

Article here. Excerpt:

'MIchelle Mills was as impeccably groomed as she was well mannered. Her nails were neatly manicured; her blonde hair sleek. Her gentle nature and diminutive, 4 ft 11 in stature seemed perfectly suited to her career as a children's nursery worker.

But Michelle's pleasant demeanour masked an altogether more disturbing personality. Behind closed doors she was a volatile character, prone to irrational behaviour and violent outbursts, as her boyfriend Edward Miller would discover.

Michelle subjected Edward to an onslaught of abuse. He was scratched, punched and screamed at until one morning Michelle, brandishing a kitchen knife, stabbed him to death in the living room of their picturesque cottage in the pretty village of Scalford, Leicestershire.

The attack was so ferocious that that the knife blade broke away from the handle. In April, Michelle was convicted of murder and sentenced to life in prison.'
