Hi op, I hope you're managing to get some sort of relief at times, your brain must be frazzeled, and your body knackered.
So much information pumping through your head, ok many on here know their stuff although their circimstances maybe have been different, you've invested many years in this union and it's going to take a long time to detatch. Your instincts are trying to protect you, your confusion and innability to make quick decisions are there protecting yourself and the children from the unknown, you don't yet have the full facts. Yes you know he's being cruel, heartless, led by someone elses influence but you do not yet know his intentions, or hers.
I've known many women in these situation hold back from quick exits and divorces to make sure finances were locked down, I mean considering how he is chancing his whole life and marriage at the moment, it doesn't bear thinking about how under the influence he is with this woman, he may make some dire decisions financially, even placing her above his own children.
This may pass, her influence may receed, how long has he known/worked with her ? because this frison will have always been there slowly changing and comparing his thoughts towards you.
What will not pass is this episode will be burnt into your brain, the totallly callous way he has disregarded your feelings, he's either completely dumb or he's a sadist.
Try not to feel pressured by pp's, only you know the level of support you have for this battle, you have to regain your strength first and at the moment he is giving you continual body blows each and every day, make no mistake this is abuse and he has a cheerleader in the form of this woman, she doesn't give a shit about you and she doesn't fear you, do not expect any mercy at the moment, they are as thick as theives.
Her husband ? God knows, does she wear the trousers, wouldn't surprise me , she seems unconcerned about his feelings, he's either affraid of conflict with your h or he's that secure and screwing behind her back, who knows but he's not offering too much support for you.
Where you need to get to, financial advice, get it sorted slowly but surely, start ammasing that information, have you much support ?, family, have you opened up to anyone.
And please go grey rock, you must understand that acceptance means severing the connection, I know you are trying desperately to keep that connection alive but it's killing you. You will reach that day when you say that's it, you will no longer share my bed, my body, my mind and you will never see me look at you with love again.
He has pushed you to this, this is the ultimatum, in your mind, the very real cut off point whereby, you will stop monitoring, will stop watching and stop hoping he will understand, this acceptance is unbelievably hard and so many on here have gone through this, sometimes without the decision being theirs, sometimes the decision was forced upon them.
All you have written is normal behaviour for a woman in pain and confused by a husband turning on them, you are normal ! the couple who are bullying, undermining and abusing you are not normal, though they have told themselves they are.
They are wicked, totally beneath you and that is ultimately what you need to understand is that you are very much better in every way than these two sub humans in your life, you must distance yourself from their cruel games.
Take care.
