My elder brother is a manipulative piece of shit who in normal situations I will have nothing to do with. My DMum is always saying 'this time he'll be different' and when we were children she often ignored his actions generally and towards me. My Dmum allows him to turn up and take advantage of her and then will bugger of.
Except this time he has been there for 3 weeks and doesn't appear to be leaving very soon.
I live in the same city as DMum but will not be in the house when he is there (far more happened in childhood than I have said)
My DNiece who is 4 lives with my DMum (her mum my sister is currently in prison)
Usually I don't do anything as brother will be there for about 2 days then bugger off except I get the feeling he is going to be around for a lot longer now.
I do a lot with my DNiece (my 2 are around the same age and we have another one on the way)
I've heard from people around that way (around where DMum lives) that there is always loud shouting/the sound of things breaking from the flat (which doesn't surprise me at all)
I am very very concerned about DNiece now and don't want her around my brother for long at all. DSis wont be out for a while
AIBU just to go and get DNiece and move her in with us (we would just about have room/money would be very very tight)? without talking it though with DMum? (DSis won't hav anyone talk about DNiece, her daughter in letters or on visits?
