Djayr,
Can you set a time period, give her 30 days to make a decision? And stick to it? Have a very calm conversation with her when she's sober, tell her that you need to move on with your life, with her sober or without her drunk. Keep it brief and very specific. I don't see any reason to make a fuss. She probably thnks it's OK for her life to continue on as is. She's comfortably drunk.
You deserve a happy, healthy life. it shouldn't be your job to see to her drinking problem.
I'm a recovering, married alcoholic. I would expect my husband to leave me if he wasn't happy or comfortable. I believe he would expect me to do the same. I think it's fair to give her time to consider her decision and be prepared to live with it.
Please, take care of you. Youre worth it.
Love from Lenina
