I'm trying not to out myself or put too many details.
Suffice to say there's a long back story (posted before under name change) I have supported my sister 100% and SS are involved with the family now.
We had a family event last night, he's never usually at these things so it threw me to see him.
I couldn't bring myself to speak to him (I can't be hypocritical) but it made me cross to see other family members (who all know the background) going over & speaking to him.
When I mentioned it to another sister she said sis 1 has chosen to stay with him & try & rebuild their lives & we should support her in that.
However, much as I love sis 1, I can't forgive & forget the things BIL has done to her & their children.
Today I feel guilty for not passing myself with him, but I hate his guts & would feel like I had let myself down if I had've acknowledged him.
AIBU to have made no effort?
I know he noticed & will have mentioned it to sis - at a previous party he hit her afterwards because I apparently ignored him (I don't recall this but if I did it wouldn't have been intentional) last night it was.
I feel bad incase I have made things difficult for her today, but another part of me just doesn't care as she had a chance to leave, a bed with women's aid but said she couldn't leave.
(I know not all women go the first time or even the first 100 times, so I'm trying to be there for her if she needs me, just not him)
