Be warned this is quite long.
I have a brother and 2 sisters. Always been close to my sisters, but not my brother.
He split up from his wife when his kids were little and to cut a long story short, he admitted to us all that they split up because he sexually abused his daughter when she was 4. My family seemed to think that it was a daft mistake he made and he should be forgiven. However, they needed to know that he also did it to me when I was 9. I told him that he should own up to what he did or I would tell them. I didn't want our family thinking what he did was a one-off.
Anyway, 1 of my sisters was supportive of me to start with, the other one did her best to avoid the subject. After all these years, I was quite glad it was out in the open and I went for counselling. Found the counselling fantastic and feel like I have finally dealt with it. (Its been locked away for years festering). Anyway, I talked with the Counsellor about my families reaction to it all and she did warn me that there may be issues further down the line that I would have to deal with, dependant on the relationship my family continued to have/or not with my brother.
Both my sisters have continued to have a relationship with him, although he does not live close and it only bothered me recently. One of my sisters (who lives abroad) offered him her house to live in (in the UK) - did it on Facebook, so I ended up seeing it. I wasn't hugely impressed, as her house is on a new estate that is full of young children. She has also told me that they are going on holiday together.
My other sister does at least try to hide the fact that she still has a relationship with him, but has admitted to going to see him when he vists our parents. When I asked her if she ever leaves her 3 year old son in the same room as him, she responded by saying - 'Of course, he has only ever abused girls'!!!
Anyway, again to cut a long story short, I have now decided that I cannot continue a relationship with either of them, whilst they choose to carry on a relationship with someone who has abused 2 children. I am gobsmacked by their total lack of support for me, as their sister. If he had abused one of them, I would have chopped his bits off and made him eat them and would never have had anything to do with him again. AIBU to have expected the same support from them?
