I wonder if any of you can advise me please. My DiL met my DS when she was nearly 40 and he didn't know she had never before been in any relationship. It transpired she had no contact with any of the male members of her family because she had a violent relationship with them. After 2 children she started abusing DS and accusing him of all sorts of things which were not true. She used to hit him and call the police and say he hit her! She has lied to everyone about me and we have lots of evidence we could use in court against her but don't want to do that as it would gain nothing and make her even worse, if that is possible. She has also hit me but denies it even though there was a witness. I am not sure if she is lying or whether she was in such a rage she doesn't remember. When we were on holiday last year she lied openly on social network about me saying things like Family Court when none off us has ever been in one. She did go to court without telling DS to get a court order to stop him going to the house but she lied under oath and he can prove it. DS has had legal advice which said that if he told the court about her lies and produced the proof she would get an automatic custodial sentence but he doesn't see any point in doing that. Revenge is not what he or any of us want.
The above is not all but enough to give you a flavour of what is going on.
What I would like to know is how to stop her lying to the children about DS and us. Not for our sake but for the sake of the children. The oldest one now asks about things she has said and sometimes we can show him the evidence they are not true. We never say she has lied but just explain whatever it is in a positive way but we can tell he knows his mother is not truthful and this really upsets us all. We don't want him to not trust his mother, we want him to respect her and feel she is truthful. We don't understand why she cannot simply accept things as they are and that the children should come first. She won't even go to parents' evening with DS and says they must have separate appointments. None of us would ever lie to the children nor say anything negative about her no matter how much she deserves it.
The children said that she tells them "Don't tell Daddy or you won't get any sweets". We heard this when I wouldn't give one of them any pudding because he hadn't even tried his dinner and he said "I'll tell Mummy" and I said "go ahead". Then they told us. This is very worrying as she must be ashamed of something if she doesn't want him to know and children should never be told not to tell, instead they should be taught that if anyone tells them not to tell their parents that person is doing something wrong and they should tell someone.
I appreciate you are only reading one part of the story but I would remind you that she doesn't get on with her father and brother and I have 2 other DiLs who I get on brilliantly with.
