Okay, a bit of background to illustrate why I'm so angry.
My younger sister was married with 2 DC, until her husband left her for OW.
He was also spending the mortgage money on OW which resulted in my sister and her children almost becoming homeless.
Fast forward a few years, and my sister now has the mortgage under control, having worked every hour she could to support her children, who have never gone without anything.
Had a phonecall this evening as apparently she can't pay her bills as there is no money in her account. Further investigation has shown that her 17 year old son has taken the money without permission. She is totally devastated and feels utterly betrayed. He's away at the moment but will be back tomorrow.
Our mother was in tears about this too, as we all thought that he was a decent kid. We really don't know how to proceed. Does my sister involve the police or punish him in some other way?
It's such a difficult one
