I've lost my alcoholic daughter to a vile abuser

My daughter is 27 and has started seeing a chap who is eight years older, who she once worked with.

She moved in with him and on certain days his two daughters came to stay, and they adored her. At the start, he seemed a nice guy, but then he began to show his true colours.

Over time, her dad and I, and her brothers, saw less and less of her and we discovered that when they'd both had alcohol, they were toxic with each other. I picked her up at all hours to bring her home and, eventually, after he'd smashed up his Christmas tree and spat in her face, she came back home.

However, he wouldn't leave her alone and we went to the police for a harassment order, but she started seeing him again in secret. He shows her no affection in public and she can't be with his children in his house, as their mum banned it.
