I'm so sorry to hear this. Addiction is horrible to deal with and it doesn't sound like he wants to not use. Can you afford an attorney? Some legal advice on assets and whatnot would be great. The burn is if you have to pay spousal support. And yes, you may have to move to another place. Smaller. An apartment. Get this sorted out. But in the end, you'll be free. That will be worth it. Your life being stable and your own (which it never is when living with an addict) will be worth it. Who pays the house mortgage? I'm assuming you do.
