Would you tell your children about your abusive childhood?

[washingfiasco]

Just that really, my children are 4+5 and due another in november. I was sexually abused as a child by my brother for about 5 years when i was younger.
my children don’t know about my brother even existing, my parents never mention him, all photos of him were taken down and we are very careful around the kids.
one set of grandparents completely took his side so again my kids dont know of their existance and have never asked about their grandads parents, but know their nan has parents.
My brother had a child with someone when he was 19 and she was 14 and my parents are heavily involved in his life.. again he doesnt know anything about his dad and luckily he has never asked (he is on the spectrum) but i think as my girls get older they will ask about how i have a nephew/they have a cousin with no siblings and i dont know whether to just lie, tell them a half story, or just be honest?
what have you done?
or am i just thinking too much into this?
any advice would be amazing, i just want to be prepared.
Thank you

I would keep it extremely vague. For example I have a sister than I am no contact with but I occasionally see her at family funerals or the like where she insists on approaching my son and saying "do you know I'm you're auntie?!" So I've been forced into giving my child an explanation (he's 10) and all I told him was - "yes I have another sister but she's not a very kind person so we don't have her in our lives anymore". You could do something similar with your children, I would NOT mention the abuse until they're probably adults and only then IF they query it as adults.

@Realisation14yeah i was thinking something along the lines of this! I know telling them the actual truth is probably a bit too traumatising. I can definitely keep it vague and simple. I think i just got a bit worked up over it thinking in ten years time they’ll be on social media and try and find things etc, worrying about the unknown i think
Thank you for your response.

Absolutely especially if it's out there on the internet and you can try to cross that bridge when you come to it but still definitely continue with the vagueness. At 10 my son is happy to accept "she's not a nice person" but in a couple more years he might ask why, what did she do? Etc so I'm just waiting for that bridge to come.
