This is completely weird situation so bear with me whilst trying to explain. So at the beginning of the summer I made a friend who also knew my brother when he was younger, well now they are together but it wasn't an easy ride, the woman had an abusive ex who because he couldn't manipulate her anymore did it to his daughter instead, she caused so much trouble that her brother came to my house to start on my brother, well me protecting my children who were inside called police, now my friends daughter goes round being horrible to my son and me. The main thing is I'm worried what is going to happen to my brother cos he lives with them now but to me I see things he doesn't and I'm worried about him being hurt
