An addiction counselor will tell you what's best for the addict and hopefully will ask what you're prepared to live with. Not as a couple, but as an individual. Motive was everything for me. I stopped enabling my daughter's addiction because I couldn't live with myself any longer. I was selling my soul to the devil, I was feeding the beast that was killing my daughter. I prepared myself to the best of my ability for whatever MY consequences might be.
My husband didn't agree and I told him he didn't have to, he has free will. I reminded him whatever he decided, it was 100% his to own forever.
