There is no stability while in a relationship with someone who is an alcoholic. You can never know what mood the individual is going to be in and you become a punching bag should the individual be experiencing a bad day. Basically you end up in constant survival mode without even realizing it. Sadly this is how it had been for your children too which is why they have needed counseling.

Once your wife left you and your children were slowly experiencing a sense of safety and piece. However anytime your wife showed up you all were suddenly thrown into survival mode because her presence was an invasion.

Part of your anxiety about court is because your wife’s alcoholism and mood changes that at time had an abusive tone is something you will be facing and she had you convinced the failures were your fault This is very common when dealing with alcoholics and addicts. They erupt in anger and can go into a rage and come at those whom they feel wronged them. It’s a VERY narcissistic disease. And they often describe partners as “my abuser”. This is the lie they live in their drunken delusions.

I personally think you should explain to the judge that you are trying to provide a healthy home for your children and you can’t afford to be expected to pay for her alcoholic lifestyle.
You can be honest about how you have tried to get help and counseling to no avail as your wife chose to isolate in her room and consume alcohol and engage online with her social media addiction.

You are so worried about what your wife will do and say when it is really her that should be worried.
