Mtn, your W is not ready to take responsibility for the pain she is in, so anyone trying to 'fix' her will be lashed out at, as you have seen. Remember, in her mind you (and maybe a few others) are the problem, not her. There realy is no way to convince her otherwise, so don't even try! (and tell others who mean well not to also)
The more people tell her what she "should" do, the more she'll want to run.
The doctor telling her about her drinking problem is good, even she knows she can't argue with that. But the stuff he said about you being father and mother should not be any of his business! I don't see how that could help.
Telling her you noticed and were pleased about the reduction of her drinking was good. But be very careful about telling her what she needs to do. That will be seen as pressure and only push her away.
It sounds like your're holding up well. Good job, sir!
M: A really long time. Crisis: 5 years. She's still worth it.
