@hisman What's concerning here is that someone who has been and is currently in recovery should understand the gravity of the situation.
While a small part of me could understand having made a one time mistake and having an ex constantly making me prove myself, THIS ISN'T EVEN THAT.
She has a pattern of behavior. One expect humility and contrition from someone who is truly in recovery - even if she had a temporary lapse.
Plus, it sounds like the court only allowing three tests in a time frame was protecting her from being subjected to a power move by a vindictive ex. And you haven't even exercised that stipulation.
I don't know about you, but I would do just about anything to prove myself to the court, my ex, my children if I had ever made such a serious mistake. Hell, I'd do it even if I hadn't even made a mistake just to be able to see my kids.
I don't think you are being petty or vindictive. I think you, as a parent, absolutely have to do this to ensure that your children are safe. Even emotionally safe from someone battling the demon of addiction. But this is literal physical safety. You would never forgive yourself for being "cool" and this time someone gets hurt or killed.
Tell them that mommy is sick and made a bad decision to break the rules and that a judge has made a decision to give mommy some time to make sure that she is well and safe.
Al Anon is a
