Welcome.
Whether or not she is an alcoholic, she clearly has a drinking problem. If that has been put on the table as a major marital issue, and she still cannot or does not stop, then it's a marital issue as well.
You've gone through a lot with her, so I think you are being fair to both of you to say "enough", and then live that as truth.
Stick around here, read more, let your head clear, get the support you need to address your issues. When you get started down the recovery road, how to deal with relationships will become a bit more clear.
