NSW: Is it possible that your anger is making it hard to see where you could improve the situation for your kids? I might have missed it, but if there was something criminal going on, KnittedScarff has a point - you need to separate this issue from your marriage/divorce. If you feel it would be something you would send to the police for any friend/family, then do it.
If you'd never do it for your own family or friends, you might want to think carefully after talking to your IC.
Therein lies the real issue. If she and I were still together I would be unlikely to even consider taking any action. But if she and I were still together, there would be no visitation or custody issues with D3 either and D3 would still be in my primary care while her mother worked and partied. So she would be in great hands.
And the crime isnt a violent or petty one...but ethically speaking it isnt something a good role model for a child would engage in for years.
And given my bad reaction to what my ex did to me/our family as well as her shenanigans over the past two months, nothing else I have on her may be enough to keep her from getting at least joint custody if not primary or full. I know, and even my ex's family (or at least her mother) believes what we have now works and is best for D3.
I will bet anything that my ex and either her father or OM, or all of them decided to do this as a way of pushing me out of D3's life and securing their role in my ex's and or D3's life. And if her father had anything to do with it, you can bet he's relishing the idea of sticking it to his ex wife (my ex's mother) by having my ex gain full custody because while D3 lives over there my ex's mother will be cut out from 90% of her visitation with D3...that's how much he hates her (and my ex isnt too fond of her either).
