Don’t feel stupid, you’re a victim of serious abuse in a number of forms.
From your recent posts it’s clear you are being financially abused and that this is part of his coercive control.
It’s unthinkable in a healthy, happy couple that one partner would scrutinise and question every transaction made by the other person if they didn’t recognise it.
This is another thing that is so, so far from normal but I think he’s normalised it so you maybe didn’t realise that?
Verbal abuse, coercive control, sexual coercion, sexual assault, rape and financial abuse. That’s just what we know about so far. Im so sorry and so proud you’ve told your friend.
It’s time to act on this now, to keep your children as emotionally safe as possible. Growing up under the same roof as this relationship means they’ll think it’s a normal, acceptable and healthy dynamic and they’ll replicate it themselves as adults.
You need to dig so, so deep for them as well as yourself and start to acknowledge to yourself that the only option best for your children is for you to end the relationship, whatever else happens x
