I'm having issues with my ex MIL and I'd really appreciate some wisdom if anyone has any.
My DS 11 has had joint residency 50/50 since I split with his father when he was a baby. In hindsight agreeing to it was a huge mistake because he is a toxic narcissist (not just throwing the term around, he really is) and his mother well I don't know what she is but it's definitely toxic. I was 19 when we met, 21 when we split, and regretfully didn't know any better.
For clarity, DS father lives with his mother, DS grandmother.
She constantly undermines me, my parenting, everything. She thinks she is the parent. She has even said in front of DS that she thinks me and his dad are bad parents. She's said because I work that I care more about money than my children (I have another DC), she said numerous times she's 'uncomfortable' with my DD (14) coming home from school alone and being herself til I get home, and she doesn't like DS being in childcare. I'm WFH now anyway.
If DS gets in trouble she will sometimes tell him things like his parents are wrong and he is right. This causes behaviour issues.
She has taken DS to the GP before without even telling me or his father, because she believes that I am neglectful for not taking him to GP for a short lived eyelid twitch. She was recently tutting because she thinks she should be taken for an X ray because he twisted his ankle playing football a couple months ago, he was seen at the time and wasn't broken, and it's v v occasionally still sore, but not stopping him running or anything.
She's encouraged DS to lie to me.
She either goes all out shouting or just creates this toxic atmosphere and mumbles or makes comments to DS. My DD has even commented she feels uncomfortable if she (briefly) has to be around her. In DD words "intense" and "unpredictable" and "0-60". My DD refuses to go near ex MIL or ex, despite ex MIL giving her money if she sees her (unusual for a teen!)
The most recent and the one which really boils my blood and worries me is that she keeps trying to take DS along with her when she's breaking COVID rules. As in trying to take him to households where there are people from 4/5 households inside, when we are in a tier 3 area. I've told her not to do this but she doesn't care. I've also told DS to refuse to go, but DS says he has to do what his dad says if his dad says he is to go.
Her and Ex argue and don't have a good relationship but he is pretty absent as a parent despite being there in person and he doesn't like me, blood thicker than water etc. He won't enforce anything or agree with me on anything as a matter of his 'principle'.
I cannot stop him going there. I've been to solicitors in 2014 and also last year about this. Unless there are extreme 'visible' issues like hard drug use etc, I've been told there's no chance of forcing any change to the 50/50 order at DS age.
My (long winded) question is ..
How do I deal with this? How do I approach her?
It's getting increasingly hard to deal with. My family and friends say remain calm and try to reason with her, but what they don't understand is, there's no reasoning with her.
After another morning of her coming to pick up DS and shouting about his clothes, that he "can't go out like that", I'm at the end of my tether. He likes oversized and vintage clothes. He has plenty clean clothes, believe me. DS was telling her to be nice and stop interfering. I feel like I'm failing my son sending him with her, but I have no choice.
