For background, I caught him cheating when our child was just one and we have been separated ever since.
The child is now 5, and the ex has been an absolute nightmare throughout, threats, abuse, lies, you name it.
I've tried mediation but it wasn't hugely successful, he sat and said all the right things then after it ended, did none of the things they suggested ( they wanted him to watch some videos and read up on how to coparent well and use a coparenting app. Both of which he's refused to do)
So the problem that I'm dealing with now is that my child is coming home saying things like ' daddy said you wouldn't let him see me on x days' and 'why did you not let me go to daddys' among other things. It's not true at all, I don't and never have stopped access, it's exs choice to see him when he does, he's even lied about being at work to avoid helping in school holidays previously. He is a compulsive liar, literally will lie about anything & everything even when there's zero need.
I'm just struggling with knowing the best way to deal with it now he's lying to my child, I don't want them having to take their dad badmouthing me & trying to manipulate them. I've thought about trying mediation again but I don't think it works, he just doesn't take it seriously.
How do I respond when my child repeats these things to me? Does anyone have any advice or experience they could share please? I'm so frustrated & worried about the impact this could have on them. I just want to protect them as much as I can.
