to SR.
I wish I had some answers for you but if you are concerned about whether your wife is bipolar the best thing you can do is get her to see a mental health provider who can properly make that diagnosis. As far as her alcohol consumption goes it sounds to me like she may have an alcohol problem. I sounds like alcohol is creating a problem in both of your lives. There are many programs out there that can help her stop drinking. I don't know if you can approach her with possibly getting help to stop drinking but if you can it might be a good idea.
I do hope it all works out for you. Let us know how it goes
