My partner has a 17yo daughter that lives with us full time- partner has decided he wants to work a job that requires nights away interstate. I don't think it's fair that his child becomes my responsibility for the nights he is away.
We have been together 2 years, but I have known his 17yro for about 6 years. Relationship between myself and his daughter was fine until she realised i'm not a cool friend, but someone who has put rules in place in our house.
My question is, do i have a right to say "no thanks" when looking after her when he isn't around? What happens if she is hurt/arrested/requires assistance from an adult? I doubt i have any say since we aren't married.
