I have namechanged for this, but i am in a weird situation. My sister is ill, has mental health problems, is still rational and honest but can also be very passive especially where our parents are involved.
Her partner is very supported by my mum, but he is jobless, can't read well and has a history of violence with a previous partner. Recently I have found out that when my sister was talking about suicide and wanting to die, he put a plastic bag over her head and sprayed lighter fuel into the bag.
He has been arrested for this. My mum is supporting him. My mum also supports his manipulation of her - eg makes her tell him when she is going to come round again when she is making noises that she doesn't want to, and then offers a lift eg 'x wants you to come around on Sat, its not fair of you to not answer him, I will pick you up at 10 and take you over' its awful but no matter what I say, no matter how much I explain or try to stop it, it keeps happening.
Her partner seems quite nice when you meet him, but if I put his behaviour into other relationships (eg imagine my friends husbands behaving like he does) it makes me feel sick, but I feel utterly powerless to do anything.
I am supporting my sister as she makes her complaint, but after a brief bit of honesty, she has now clammed shut 'officially' and says she doesn't want to make a complaint. He will easily get off if he plays the 'she's mental' card.
I just don't know what to do. My name change is sort of black humour. None of these people seem to share any of my values, nor can they see how fucking awful the situation is - its so weird. My parents always seems to side outside the family and never support their children - even my dad supported my sister's husband when he tried to take her house and children away leaving her nothing.
I really wish I knew where to start - I know that if I was in some families her partner would have had his legs broken and forced to stay away sometimes I wish I didn't have faith in agencies and did take action like that - I wounldn't feel wrong.
I don't think any excuse is OK for my poor sister with her head in a bag of lighter fluid, but am I being too defensive?
