I'd like to know what you'd think about this. I hate my ex mil. She is a large part of why I split with exh. False allegations to social services and a lot of lying on her part. She and exh and her h have just taken my 5 year old on holiday and he has come back saying that she told him mummy lies. This is not an isolated incident and I have warned them about appropriate conversations with my son. This was basically about a conversation I had with my son about me getting grey hair and I said that it happens when you get older and that exs mum and my mum both have grey hair and colour it. Son obviously told her just part of the story and that was her response. For what it's worth she is almost 70. I worry about her repeatedly saying these things to my son and what effect it will have on him in the future. I want stop overnights but need to know if that is the right course of action.
