hi and welcome-
i have to agree that what you've described, in my opinion, goes beyond drinking....she sounds mentally unbalanced.
i had a friend who behaved like your wife...she finally was diagnosed as bi-polar and was under the treatment of a team of psychiatrists...
that didn't stop her tho...all she ended up doing was her meds PLUS the drink...
i finally had to walk away...
what i have learned is that many addicts are quite resourceful...we think they will not survive without our help but in my experience, once i walked away, i was quickly replaced by the next eager enabler...
