I know this wasn’t normal but I’m not sure how abusive it was.
When I was at university and living with my boyfriend, he would go out to work during the day and take the keys with him, locking me in in other words. It was a flat so couldn’t get out via a window or similar. If I tried to protest he’d demand to know why I wanted to go out without him.
Now I’ve written that down that’s pretty bad isn’t it
