I think MIL'sissues come from far further back.
Her Mum left when she was a toddler, her dad put her into care for a year. hence she ahs no idea of what being a Mum is; she amrried an orphan but one who had been adopted into a loving family with a Mum who was the ultimate matriarch (from dh's adotring descriptions, never met her, died before me).
So she had to share hr home with MIL for several years, and when MIL moved (they bought her out) she had the same house. Funnily enough first chance she got she sold it- this led to her marriage collapsing after 35 years!.
I am not convinced she even really liked FIL so her sons were everything; not that she was fab Mum- when DH was 17 he tried to kkill himself and she stopped him geting help becuase ofn what neighbours might think , she wouldn't speak to BIL for a year because he split with his drug addicted well off fiancee, and she had a very clear life paln: DH was to stay with them, but the house so they had extra retirement cash, never leave; BIL was to marry soemoone well connectd, have two daughters and live close by.
Well DH met me and e have 4 boys, she tried todestroy my wedding and has called my disabled son a freak as well as many oter things including ringing up DH after another suicide attempt and telling him he had a cheek as it was she who ahd all the problems. Oh and trying to mke us give back a wedding git of £2k when I was on mat leave and dh had lost his job, and telling my autistic then 5 year old son and his 4 year old brother that FIL had hit her- on a day when DH was there and he certainly diod not; he'd walked in, they'd argued and he had walked out.
BIL id stuck at home, had to buy half the hosue just to keepa roof over her head and now is stuck there with a stupid mortgage and plummeting house price. She won't allow (FFS- he's 35) him to have a GF at home so his relationships fall apart rapidly- no money,only driver in the house so at beck and call and no GF at home. Priceless.
She ahtes me, she thinks I stole DH (he was 27 and desperate to leave when we met). She sent FIL to talk me out of my wedding when dh was on stag night (we already had DS1 then), caused a scene at the wedidng and all sorts.
DH ahsn'texactly been a good boy about it all- he descriobed her on TV as the worst MIL in the world and they wanted her in to discuss it. Of course that was me - I refused to give her cntact details etc- dh ahnded them over! But its me with the evil reputation.
Last year after severa years apart I arranged for them to get back together: she'd never met ds4, dh didnt even tell her I ws pg althogh did text when he was born and she didnt reply (BIL did but she monitiors his calls so text only. Yes I do think he should get a small flat and a backbone). We all trekked over, many miles, for a quite nice day although having to BF baby in the nastiest pub toilet imaginable as she'd arranged lunch there was horrid. Se hates BF, makes it very ahrd for anyone- used to shut me in her bedroom with no heating in December when ds1 ws born with IUGR.
Anyway seemed OK even if she were panicky (has OCD) about the boys, but she went quiet after. Then she got really nasty on the phone with dh suddenly and its obvious she was looking for an excuse but couldnt ahve me looking good when I brokered a reunion by saying no. A few montsh alter her Dad died and she called DH: Dh had been asleep an hour after a night shift so apparently didnt repsond properly (- I ws there he was fine). Weleft numerous messages after about the funeral, arranged chidlcare (NOT easy), but she wouldnt reply to tell su when funeral was. Well we knew day from BIL but not venue or time, and its a massive drive so dh didnt go (didnt get on with Grandad- Grandad had a massive go at him at the wedding for settling down, he ahd 8 kids by 6 women). On the evening of the day DH phoned, was sworn at for not being there (??) and told never to contact her again, so he won't. I willt ake his led: if he wants to then I will back him up. I'd never say you mustnt speak to your Mum.
She sends presents for the boys at Christmas etc but not DH; its hs first birthday since the fall out in 3 weeks,am dreading it when his own Mum doesnt send a card.
I'm no angel but have done all I can, she manipulates things to make herself look a victim as she is a martyr. She does have a direct link with dh's depressiona nd its beeen controled when she's not been around. At 17 his first breakdown was caused by her making himwork FT (for stonkingly high rent), hewas studying FT for a Uni place that he was too ill to take up and she'dwake him after a few hours sleep to use him as a taxi for her business. DH put up with all that but when she called ds1 names that was it.
So maybe I come across as mean about my MIL but I keep it to here and TBH she is appalling. DH gets n fab with my Mum so I am just trying to learn from them instead.
