Absolutely FUMING with ex MIL

Hi all

I have an 8 year old ASD DS and split up with their dad when DS was 2.

For a bit of backstory - my ex MIL had always been an absolute nightmare, constantly going over boundaries and being horribly verbally abusive to me in the past. For the sake of DS, over the last couple of years, we have became "civil" to each other when we see one another.

Since my ex husband moved out around 6 months ago from ex MIL house, she has been obsessed with having DS at her house. Which I didn't mind until the lack of routine between 3 houses (mine, his dads and granny's) was having a negative effect on his behaviour.

Recently, getting fed up of DS arriving back to me in horrible form and displaying bad behaviour (he needs routine as part of his ASD), I told his granny that stays at her house will not be as frequent, with school starting soon and that moving forward, DS wont be staying there on a school night, but he can stay at her house for one night at the weekend, if she would like.

Ex MIL seems to have taken this badly and using now anything she can to see DS.

His dad collected him today after work for a few hours before dropping him back for dinner. He said his mum had PHONED OUR GP AND MADE AN APPOINTMENT FOR MY DS WITHOUT MY KNOWLEDGE.

Apparently, its for his "allergies" which he already takes Benardyl for which WORKS. And for the fact he cant do his poos properly (he refuses to go unless its in his granny's toilet, some weird OCD thing) which is currently acknowledged by his ASD support team and we are working through coping strategies etc with him. I have already been told there is nothing GP can do for this as the psychological mindset is part of his ASD care team.

What steps do I take now?

Call the GP surgery and tell them only a parent can make an appointment moving forward?

Do I remove all access to toxic ex MIL until she learns some boundaries? (Hard to do when DS dad will just ignore that anyway)

I am LIVID.

Any time with MIL should come out of your EXH’s time. Thats just straightforward - he doesn’t have three parents.

Surely she can’t make GP appointments, she’s not a parent!

Are you facilitating her having custodial time? If so, stop that. She can see your child on his dad's custodial time only. That's the future, period, not her taking your son on your time. You've enabled her overreaching and thinking she's a third parent. A 3 way custody split, which it sounds like you've basically had since ex left, is not in his best interests.

Password protect your son's medical files. You'll have to speak with the office and explain a non custodial person is trying to make appointments and get information.

I think this is what it will need to come to. I dont want any contact at all with ex MIL.

Id just send her a text saying going forward its best she arranges with your ex in his time with DS to see your DS due to getting him into a good routine which is needed with his autism.
and then block & ignore her.

Has your dp got parental responsibility?

Do you mean DS dad? He is my ex husband so not my DP but yes, he has parental responsibility as well. Our split is about 70/30 to me in terms of care.

DS dad wasnt informed about this beforehand from his mum either.
