So about a year ago my step daughter moved out because we gave her a choice. She either respect the one boundary we set, which was for her to be home by 1am on nights she has a college, which was 2 night a week, or she moved out. She chose to move out be Because she felt out 'rule' was juvenile and Ridiculous and she refused to respect it. She was 18 at the time. There's much more back story, bit that's the crux of it.

She has come to stay with us over the last three weeks because her and boyfriend broke up and he asked her to move out. She disappeared into a park with a razor blade and a pack of pills. I drove around looking for her, found her, and took her to the urgent mental health care centre. We said she could stay with us until she sorted herself out. That was a month ago. She's started hanging out with the ex boyfriend. Within a week of what happened he'd given her presents, bought her stuff, and agreed to drive her places, and they're still sleeping together. We don't understand why she would want to be with a person that made her consider killing herself. We've expressed this concern. She brought him to the house last week and I wasn't ok with it. We told her we don't understand their relationship and we don't like that she still sees him. We told her yesterday we don't want him coming to the house. We respect her decision to do her own thing and see him, but he's not to come to our home.

She has gone off the scale. Saying how dare we make assumptions about their relationship and about him individually. How disrespectful we are. How she's an adult and deserve mutual respect (she's 19, flunked school, and she lied about her results, none of which we've made a big deal about).

I'm completely incensed by the face the she demands this respect while disrespecting our hospitality and wishes in our home and I'm at my wit's end on how to deal with her.
