Aww op big hug here,
What a situation to put you and girls in, he knew this and rolled with it till the time was right for him to drop the bomb,
So the car, does it have a ' cooling off period ' were you can cancel it, get the money back to pay the bank loan back, may have to take an hit on that but most of it could be paid back, one less thing to pay for maybe,
Ask advice from mortgage company, explain what's happened, they will help/ support,
You don't need to know the reasons why, ' I think you know we know ' it's done , he has left you and children finically crippled, what a selfish man, what am trying to say is ' this can not be forgiven op, so it doesn't matter about the details for now' you have to sort out the finance's, protect the children and look after yourself to enable yourself to do this,
Hit him were it hurts ' the nice shiny car'
Try to stay calm, grey rock, take note of everything he says and does,
Finically you need guidance and support, around the home situation,
You will get though this op, right now your broken, but you will find your anger and ride this wave,
Good you have your mum this weekend, 💐
And lots of advice on here 💐
