I have a DS (13) and have been separated from his dad for over 12 years.
Ex introduced a girlfriend to DS in October and announced they will be getting wed next July. She is a widow with 3 children, 2 older, in their 20s, 1 DS (let's call him Sam) who is doing his GCSEs this year. Sam's dad died when he was 11 just before lockdown.
The first time our DS met her she gave him a t-shirt on with 'I'm the favourite child". She is a trainee child counsellor. She was very OTT ingratiating with DS which gave him bad vibes and my advice to him was she is probably anxious to make a good impression and she will chill out in time.
Ex was due to see DS for a full week before Christmas but reduced it to 48 hours the day before which I was puzzled at.
Xmas Eve my DS pours his heart out after coming home from his visit to his dad's.
The new Stepmum to be had disinvited him from her family christmas party over a row she had with his dad hence the shorter visit.
It transpired that on a visit to her house our DS (13) and her DS - Sam- (16) had a conversation where my DS felt hers was being anti-black in the way he was talking about knife crime. My DS asked Sam if he had a favourite race.
It was a very facetious question, based on the fact that my DS had bristled at the sense that this lad had an unfavourite race.
Sam had then reported to his mum that my DS is racist.
The stepmum to be then reported Sam's version of events to his dad as gospel expecting my DS to be disciplined.
My DS got hauled over the coals by his dad. My DS explained the older sister of the lad and her boyfriend who were both in the same conversation had laughed at his question and got that it was a bit of a sarcastic joke.
Stepmum spoke to her daughter and despite her backing my DS, stepmum fuelled the row further by saying our DS needs to understand he can't make jokes like that to her son because he is autistic. When my DS's dad defended him she said my DS was no longer invited to her christmas party because he was too immature. She then sent insulting texts and split up with DS's dad.
Now it is all back on because she apologised saying her meltdown was due to not having her ADHD medication and can't control her impulsive behaviour without it. Now I know this, it has started to dawn on me why my ex was getting married next year to someone he had known for 4 months.
My DS is now very wary of her. He didn't want to go to his dad's after Christmas because he was told the stepmum wanted to have a 121 with him about what had happened before christmas. I sent a text to his Dad to ask for no "X family drama for DS's birthday please". She was there for my DS's birthday but he avoided being alone with her. My DS has said she likes to talk to people as if she's a psychiatrist to try and diagnose them.
So more WWYD than AIBU - I feel like autism and ADHD are being used as both a sword and a shield by this woman and I don't know how I approach this and keep my DS's relationship with his dad.
(Background context so this doesn't come out downthread: My ex is undiagnosed as autistic, a very clever and sometimes kind man, who struggles with understanding people.
Over the years since we split it sounds like he has come to embrace his autism but has never sought an actual diagnosis.
Our DS has autistic tendencies (stimming, obsessions, loud noises, certain fabrics) but to a much much lesser degree than his dad (socially our DS does well at school) and my approach to this has been to focus with him on understanding himself, calling it autistic tendencies or traits rather than one big label and not to go down a formal diagnosis route (we were told it would only result in giving him more time during exams and he finishes too quickly already). We also watched the secret life of 4-5 and 6-7 year olds a lot when he was little and talked about how people react to what they feel and you can't see feelings but you can work out what they are, yours and other people's and it's a secret language for everyone to a greater/lesser degree however intuitive or empathic you are). PLUS I am in remission from cancer that killed my mum and sister in past 3 years. I am starting to lose it at the thought that DS will be trapped with this woman as a replacement for me. She is moving in with ex soon but after the row she is leaving Sam to stay at her old house with the 2 grown up children and dogs to look after him - I feel pretty sorry for Sam in all this too)
