raspberry just as narrow minded on the other side too. Not every experience involves a mother doing everything she can to protect her dc, and suffering the consequences after leaving.
Without wanting to minimise your experience chloe it isn't the only one. Not all parents are victims, some are just cunts.
Stand by and watch your wife abuse your dc. If it gets too much, stay out as much as possible because out of sight, out of mind. When dc gets to toddler age and is capable of trying to follow you out, shove them back inside. When they get to school age and can grip desperately on to you, peel their fingers off, slap them and throw them off if needed, just get yourself away for a bit of peace. When you hear them screaming and begging in the night because your wife has woken them again up to tell them she wishes they were dead and all the reasons why, turn the tv on loudly.
When they are 8/9, and even your wealth isn't keeping suspicions away, let your wife scare them from saying anything. If listening to the graphic descriptions of the gang rape and torture your child is told happens in care is a bit traumatic, go out.
When your teen starts avoiding the house, and appears to have moved into friends/ the farm buildings, encourage them back because it makes life easier for you if she vents at them. At this point pets, and having always had them for comfort is the only reason your dc isn't either dead or completely insane. Listen to your wife threaten on a daily basis to get rid of them before dc comes home from school. Make your own vague comments about how it would be better all round if dc didn't have ponies getting in the way of supporting their mothers mh issues. When she covers dcs bed with disturbing images of animal cruelty and you realise from the hysterical violent self harming it might have gone a bit far, tell them it's ok because you'll make sure they are given to other children, not the meat man or a third world country. Cite this forever more as how you protected them. (Genuinely sad thing is he must have intervened and she listened because afterwards the threat was always about giving pets to nice dc that deserve them)
At no point do anything else to intervene, don't throw your wife out of your home, don't report her, don't be open about what's going on, don't use your considerable wealth for divorce and custody. Why bother with that shit when it's easier to do nothing.
And if dc ever try and discuss it, silence them and say 'they don't understand'.
I'm with op, in my case 99% unsupervised contact would have been an improvement on living it 100%.
