The BBC could have framed this better but this is an interesting discussion of Clare's Law: Does your partner have a violent past? Are you at risk? Clare's Law allows women - and men - to ask these questions of police, who can also use it to offer information to people who have not sought it.
The opening story is an insight into people who accept a partner's version of events in previous violent relationships and therefore reason that the violence won't recur because they won't be like the previous partner.
When the violence did happen again:
When his attacks came to a head and he was arrested, she expected him to admit to police what he had done.
That he didn't was the turning point. When police offered her information under Clare's Law, which she had never heard of, she accepted.
She discovered her partner had told her "nothing like" the full picture.
"My chin hit the floor," she says.

The later part of it has useful insight from Becky Rogerson:
As domestic abuse charity director Becky Rogerson points out, a visit from police can be dangerous for some women.
The chief executive officer of My Sister's Place in Middlesbrough and interim director of Wearside Women in Need says this makes it difficult for those with coercive and controlling partners to receive help.
"Even if they're not responsible for calling the police, they often get blamed," she says.
"I think a lot of women would be very worried about the police just ringing them and asking to speak about the guy that they are already frightened of."
In Ms Rogerson's experience, if a woman "feels she's not able to escape" it can be "easier not to know".
"They always think, 'if I do something, or if it gets known, then social services are going to remove my children'," she says.
"We hear that over and over and over again - women are always terrified of social services."
