I was trying to think if I would have had 'evidence' if I had had to prove my ex was abusive. Not much but more than Helen.
Both my parents had seen him shout at me.
His kids had seen him shout at me and corner me.
But then they would also have seen me snap and shout at him to leave me alone.
Colleagues had seen me 'react' when he phoned me.
His neighbours had witnessed him throwing me out and calling me a cunt repeatedly.
My dc saw him push me over. (Too little to be witnesses though and not reliable as they claim to have seen him kick me - not true).
His ex could testify about what he did to her. She might choose not to.
And I would have had plenty of abusive texts and emails.
Plus I frequently told friends he was a bully.
But I reckon that might get me a restraining order at the most. I doubt it would be enough to have him charged let alone convicted.
So I'd give Helen a snowball's chance in hell. (If this were rl and not what I now know to be a ridiculous soap)
