I’m sorry if this is long, I’ve got no one irl to speak to and my head is going 100mph.
I’m the youngest of 3 sisters by 10 yrs, different fathers. Each of us were in care by our teens and each of us are NC with our mother, me for 15 years, DSs for 25+, they are also NC with each other for around 5 years over some spat I’m not involved in.
This weekend was DS2’s birthday, we had a little get together at hers and had a few drinks. We were doing our usual tipsy rant about our mother and out of no where DS spills that my father, their stepfather, had sexually abused her and our mother knew. She didn’t go into gory details, she was actually quite casual about it and carried on the conversation. BIL didn’t flinch at this news like he already knew and it hadn’t really registered with me, but today it has. For background, my father was a piece of shit, he was incredibly physically abusive to everyone and was a raging alcoholic/drug addict constantly in and out of prison - but he was good to me. He died when I was a child. I personally had good memories of him but I’ve always been very aware of how he treated others and what an awful person he was. It’s also been hinted before that he tried to drunkenly assault our other DS but the conversation was quickly quashed and it’s never been mentioned again.
I absolutely believe my sister - I myself was sexually abused by another step father and our mother knew about it, in a way she was even complicit - but I selfishly feel horrific, I have no idea where my head is at. I’m lost, I feel almost deceived. I feel guilty that my father did this to my DS2 and possibly DS1. I cannot bring this up with DS1 as she’s a very closed book and won’t have his name spoken in her earshot, I also don’t want to involve her in DS2s business given their relationship. My sisters have took care of me since a young age, we don’t have a typical sisterly relationship and at times I’ve felt like a burden to them..like they didn’t actually like me or want me around, but we’re obligated to. And now it kind of makes sense.
I also suffer from bipolar which is usually managed but once an episode starts it can be difficult... I’ve been sectioned before and suffer from suicidal ideation even during good periods - right now I can feel my mood turning. I’ve milked the ‘hangover’ today so DP has took over handling the DC, but I can’t tell him as he already has an awful lot on his plate, right now I’m supposed to be his support. I have no idea how to handle this information, whether it even needs ‘handling’, and how to process this guilt and shame that have suddenly hit me. My father is dead, there’s no chance of justice. I don’t know why she told me or why so flippantly as if it was a regular conversation we have.. I don’t think she’s told me to open up any future dialogue about it, we don’t have that type of relationship, we’re not that deep with each other. Both DSs are strong, smart women who had every reason to take wrong paths and neither did, I feel so sad for them that their childhood/teen years were so much shittier than I’ve ever known.
What do I do? I’ve always known my father was a piece of work but now he’s not just a thug, he’s a paedophile, one who abused my sister/s. I look like him too and right now I want to tear my face off.
