i know this didn't happen to me but i am very close to my mum and i know the pain she's been through with it so thought i'd share to help you....
my mum was abused as a child by her older brother, he was the oldest by a good 5 years, and of 6 children my mum was the youngest...he used to sexually and verbally ubuse her while he was 'babysitting' and then would put some pennies under her pillow and say it was her present for being such a good sister.... it started when she was about 5/6 so she didn't realise it was wrong.....it continued until she was about 11....hapening once a week or so when my nan had her night at bingo, she was none the wiser, and at the time it seemed the other brothers and sisters didn't know what was happening either....
well when my mum was 11 he moved out of the family home to be closer to his work (as he was now about 25 i think)....and my mum didn't say a thing....even though at that point she'd just realised it was wrong, but after it had been going on so long she thought it was her fault for letting it....
she is terribly scarred by everything that happened, and still even now (30+ yrs on) has periods of depression caused by this. I remember as a kid we were allowed to socialise with him, nothing had been said about what happened still but i always felt tension from my mum when my uncle was somewhere....then one day when i was about 6 or so i remember we were all at another aunties house and he gave me some money in the garden and said it was for being a good neice, and i should go in and ask my mum if he could take me to the shop... i went in and told my mum my uncle had given me the money and why and could i go to the shop and she just started crying, asked my other aunty to look after me and my 2 sisters (them being too young to remember at 3yo and 1yo)
mum went outside and confronted him, then came inside and we went home, he was pleading with my mum for something, i didn't know what at the time, but mum's since told me it was not to tell the family..... we never saw him again, but the week after that all happened my mum sent a letter to her mum, and her siblings outing him for what he'd done and hoped it would help her have closure and explain why she didn't want him near her or her family....it seemed that the way he gave me money and the reasons he gave it me reminded her of what a horrible horrible man he is!!
said uncle is currently on his death bed with cancer and has only been given 6mths to live but none of the family wants to know, it seems he did the same thing to 3 of my mums other siblings too, and it's since surfaced that he did it to one of my cousins who lived with him during the week so he could attend a better school that he got a schollarship for.
my mum and my other aunts and uncles think its their fault for not saying anything earlier....
i'm not saying this man IS going to harm your dc the way he harmed you but it happened in our family....and people who do such horrible things should not be allowed to feel you have forgiven them just because you keep it locked inside, by coming on here and asking advice about this just shows you havent and you are not ready to forgive him for what he did. if having your child in his precence makes you feel weary then that is the best way you can realise just what he did to you....you need to speak to someone in your family and tell them what he did, you cant keep it bottled up, and if you found out he'd done it to someone else since you'd end up blaming yourself for it like my mum does with my cousin!!
i hope you can find a way to deal with this and get this man out of yours and your family's life....IMO what he's done to you (no matter how bad, its hurt you) its unforgivable, you were a child!!
