HELP, my partners daughter is 18, her mum is moving away so she wants to move in with us, it's just me and him and I like my own space. I don't know her that well as she has only called occasionally even though I've been with her dad for 9 years, it's making me very anxious. I feel like I have to say yes coz I'd do the same for my kids but it's putting a massive strain on our relationship also how much per week should I charge her for rent? I'm annoyed coz I wasn't involved in the discussion she asked her dad, he said yes and then didn't tell me for months until I overheard a convo between them discussing bedroom furniture. I feel like splitting up and getting my own place, my heads in a whirl.
