Sister been with her abuser for 4 years, he's very controlling. I don't speak to him due to previous arguments.
She's tried to leave him several times but goes back to him for her own reasons.
She tried leaving again this week but got back with him today.
When she 'leaves' him me and my mum help out, put things in place, support her etc in the hope she does leave him. He's smashed my mums windows before for phoning the police when he assaulted my sister.
I just don't know what to do? I obviously don't want to go no contact with her but my mental health can't take it any more. It's causing me so much anxiety.
Social services are involved.
I feel sorry for my mum.
Any advice?
