I have one full sister and one half-brother and sister. Me and both sisters share a mum and grew up in the same house, although there is a 9-year gap between me and my half-sister. I have never seen her any different from my full sister. Even writing half here feels wrong, etc. My brother is a different story to the point I dont even see him as a brother, really. My dad very much got himself a new family, so I didn't really see him much growing up, etc
My brother wants to form a relationship with us. He doesn't have any other siblings apart from us. I do feel for him but he's a stranger to me really.
Don't know what to do
