Hi,
I only joined yesterday but two people commented upon my story and it seems we all go through the same things. I still blame myself and my mum is similar to yours, she takes pity but I have heard it all before. I think by the sounds of it there is nothing you can do that you have not already tried. You have your own children to think about and if he can steal of you all, I am sure he is capable of stealing off your children. Maybe chat to the two ladies who contacted me, they may be able to guide you further. I actually felt a little relief being on here yesterday as I am too ashamed to talk to friends etc. Maybe you won’t be able to help your brother but you can help yourself.
