Four years ago.
I stayed with a woman for a month, who had a fifty or so year old man living in her entire living room. She was paid £400 or so a month by the government as a DSS tenant, but they paid him and he only gave her £320.
She had a low paying job and had to rent out other rooms. He would intimidate the other female flatmates so that they would leave and it was just him and her. He had no respect for her, blasting sound from games and TV when she was above him, trying to get sleep for an early shift. He also smoked cannabis in the house against her wishes, bought a dog into the house when she had two cats and pinned her against a wall by her throat (he was arrested but released without charge hours later). He even had people try to frame her for a crime when she had saved him from a stroke. She also found her nightgowns to be stretched be one night and it was assumed that either he or another woman had tried it on.
Anyway I moved into one of her rooms and she came onto me. They had very intense verbal fights, I had to step in when she hit him and he was about to hit her with a snooker cue that he snapped over his knee. He didn't start on me directly but the fights between them shook my nerves, especially as she kept telling me how unstable and violent he was. In the end he started to call me names, I wanted to smash him in but knew that he was armed with a knife, so I wanted to batter him with a hammer. I knew that it would get worse if I did nothing.
So I found a room on the other side of the county.
She came with me after a few days apart and despite her repeated appeals on phone and in writing to the council, they kept fobbing her off and telling her that they would find a place.
She was served with a bankruptcy order soon after. She lost the house and all of her possessions, save her Buddha's, a few clothes and a bit of furniture. He was given a one bedroom flat by the council as soon as he was booted out and has his entire life paid for by the government. The landlady and I have been together ever since, bouncing from room to flat, to flat, to flat.
I won't even step into that town. I don't know what I would do if I saw him again.
