My DP's brother is 48 and lives at home with MIL and always has. He holds down a basic job. He had no friends and has never had a girlfriend or been on a date. He's intelligent (has a degree) and he's attractive. His social skills are not great - he hasn't got much to talk about and says awkward inappropriate things - not sexual but more rude and abrupt.
I don't like the way he is around DD who is 3 and DS who is 2. He is very physical with them and plays tickling games and has them on his knee all the time. He has never been left alone with them but one time I was at DMILs and she popped out and I was alone with him and kids. I was busy with DS who was a baby and he took DD upstairs to the playroom. Nothing happened as I kept looking in and they were sitting next to each other reading a book but I didn't like it and I kept saying it was time to come downstairs but he ignored me. That rang alarm bells with me.
I'm not sure whether this is just poor social skills and him not realising the social rules and how careful a male relative needs to be around young children. Or something more sinister. But I don't like it and my alarm bells have been going off every time I see him with them being so physical.
I mentioned to my DP in the nicest possible way I didn't like it (i sort of made a joke about the brother ignoring me in saying it was time to come down) but he thought I was being ridiculous as its his brother and he totally trusts him. Anyway I got DP to agree that the kids would never be left alone with any man as a way to prevent anything (I'm actually happy for them to be alone with some men, just not creepy uncle but a blanket rule seemed easier to enforce).
Tonight we were round at DMILs and she wasn't home yet. We were having dinner there so I popped to the shop for some stuff. So just DP, brother and kids there. I was gone 40 mins. Get back and DDs sitting on couch opposite uncle on his chair with no pants or trousers on and legs spread. I was totally like WTF?! I said very loudly DD why don't you have any pants on. Uncle says oh she had wet herself. I take her out immediately and find DP in the garden doing some chores and ask him why DD has no pants on in front of a man. Sorry he says, she had wet her pants so I took them off and got distracted doing something else. I said it was totally unacceptable and he was a bit sheepish and found a clean pair of pants. DD then says it was fun sitting on my uncle's knee with no pants and getting fresh air on my vulva (both children know the proper names for their parts as I had read that being able to name the parts reduced the likelihood of abuse - I looked this up specifically as worried about the uncle. We've also read children's books about how our parts are private and no one else should touch them etc).
I've decided I want to seperate from my DP for many reasons but I'm worried about what might happen with the uncle when I'm not there. DP is weak, people pleasing and will also lie to avoid confrontation so I can't trust that he will supervise his brother with the kids. What do I do?
I feel I cant stay with him just on the tiny chance something bad happens as I'm miserable. But how do I protect my children when I'm not there? I realise this post might make me sound like a nutter but I don't have issues with any other male relatives or men in general. Other male relatives don't act like this either. And I have a particularly good radar for people so much so a large part of my job is choosing which senior executives to employ for companies I consult to.
I actually feel sick about this. What can i do except make rules that might not be followed and teach the kids about keeping safe.
