Ok, will try to keep this short without too much non essential detail.
I have two dc with ex one has SN.
Ex has a drink problem. He does not drink during the day or anything. He is what I would call a functioning alcoholic, holds down a decent job etc. I would trust him on say a day out with the dc. However as soon as drinking comes into play and he and his family drink A LOT, he becomes incapable and will literally drink until unconcious. He drinks into this state almost every night. It was the main reason we broke up.
His family see no problem with his drinking. His Mum in fact is pretty obsessive with enabling the grown up drunk adults in her family to the detriment of dc. Ex H agrees this to be true. Eg one night ex disappeared from a family night out to go off on his own. She came home in tears and immediately jumped in her car to go and find him despite being very drunk herself. On another occasion she left my ds (2) at the time in the care of a passed out drunk adult to go and look for another of her children. I was unaware of this until afterwards. Another time ex woke one of my dc up for a drunken "chat", I realised and went into stop it and his Mum became quite angry with me and tried to make me leave ex H with ds chatting drunkenly in the middle of the night because she was worried that ex H would go out again if he didn't get his own way! Ie once again prioritising a drunk adult man over a child.
My questions are this, I stayed in the relationship for much longer than I should have as I have because I was too scared to leave knowing they would now have unsupervised contact with my dc once ex and I split formally. Is there anyway now that we are coming to divorce that I can insist that my children are not left unsupervised with these people? I do not want them to stay overnight or go away with them and this is something ex is insisting on? Has anyone any experience of a similar situation? Any thoughts please? What would a court or solicitor think of the examples I hav given here? Thanks.
