Welcome flyaway. Do you know any lawyer to talk about this possibility? I know laws vary by country/state. No need to make any harsh decision but having your options more palpable may give you more peace.
I am so very sorry for what you have gone through. I believe it is brave to keep an addict from the possibility to waste all the hard earned money in his addiction.
May you have clarity and light on your path. Please take a look at the "Classic reading" sections in the Sticky section at the top of the forum. There are many safety tips. Take care of yourself and know you are among friends here.
