I continue to be concerned about your reactions to this, or non reaction... I'm hoping its a posting style rather than a reflection of your state of mind.
If not, you sound paralysed with fear/ inertia/ disbelief, and that is not good. For you but also for your children.
What are you hoping will happen?
That your wife will suddenly change if you carry on doing nothing/ the same old stuff (?), and your children will miraculously be able to recover from the trauma and come out unscathed from the damage being inflicted on them, and you, err, what? Do you forgive her abuse and just swallow the events of the next few months? Where are you in all this?
Abise can take away self esteem and the belief that you can do anything without the abuser agreeing/ permitting... And it can seem like the only way out is to placate or try and get the abuser to see reason and change the situation themselves.
Trouble is, this doesn't happen.
What do you need to get out of this inertia? And to step in to protect your children? What are the steps that will help you to unstick yourself? What's stopping you?
Can you engage with that rather than getting stuck / drowned by each incident - that way won't help you or your children get out and into a safe place away from this awful enviroment.
Bottom line is, you can't make her change, and its futile to expect her to resolve the situation. You can only control your own actions and reactions.
