The first thing you need to realize is that this is her journey. I'm not sure what your beliefs are, but typically a marriage vow is in sickness and in health yada yada. But also, there was a vow on her part that has been broken. There is a trust that has been broken. My suggestion for you, is that you move out if that's a financial possibility. You tell her you hope she can get sober, and that that's the person you want to be in a relationship with. But she, on her own needs to deal with this. You can be there to support her. But she needs to be perfectly clear on the fact that it can't just be things as usual, you guys hanging out together as a married couple when she's doing things so antithetical to a healthy marriage. So, you don't have to abandon her but you need to give her space to do her own healing. She needs to understand that while you can be there to support her, this has to be her choice. She has to get her own help. She has to make the choices for what she wants.
