I've been following all your threads and posted a couple of times before but I had to change name to post this time.
You are a very strong woman and your strength will grow bigger with every step and now the penny has dropped, you will notice more and more abuse/training on your girls. Your last few post have brought even more tears, despite having learnt to bottle it all up. I hope my experiences will you give you the heads up about seeking minimum contact between Twatchops and your lovely girls.
I'm posting as an abused child, who fled a country to escape my, now estranged, narcissistic mother. I went No Contanct the moment She started on my DC1 and She has never met my DC2 (and never will, if I can help it). When my parents separated it was a relief at first: it was an end to the eternal arguing, sulking and losing my bed to dad when his back was bad (otherwise he slept on the floor in their room- She used lock the lounge, so he couldn't have the sofa). My dad left Her, thinking he was the one provoking her but once he was gone, it was me who provoked her. I didn't 'clean well enough', 'iron well enough', 'do you call this dinner?', 'why is your sibling not well behaved?'... When I left, she took it out on my sibling...
T'chops's whispering game, reminded me of my mother eventually convincing us (sib and me) to refer to dad as Monster. Monster did all sorts: from spying upon us to not paying a penny (and a lot more, apparently). Before visiting relatives she prep'ed us in asking probing questions about relationships, finances...And when we came home: it was hell if we had a good time because Monster gets to play spoiling game, whilst I can't afford to feed you. (we came home with shopping bags full of food)
She succeeded in separating us from not just dad but the rest of dad's family for a fair few years...until I moved away (ah!Shedevil!)
T'chops's re-organisations of the keys (or books, shoes, bag)... It still makes me doubt myself every day; I'm sure I have locked the back door, at least twice, but the slightest interruption whilst I'm getting out and I might have to turn the car round and send someone else to check and then I still don't trust them.
One last thing: my mother was well aware on not leaving the tiniest visible bruise but she still hit us (we never, ever, ever let grandma or auntie wash our hair)
I'm so sorry, this is a very long post. You have the advantage of being the normal mum with an abusive dad. Good luck on your anniversary.
