I see your concern but "not drinking for 6 months" is NOT the same as getting "into a program" or getting "counseling for the PTSD and the alcoholism" or being "present as a parent 24/7". So just stopping to **** you off does not actually meet the requirement. What will be different about telling her one more time that you're concerned? She hasn't done anything with the information so far, and she's had it for awhile.
I think though it is worth considering...what would happen if she did follow the ultimatum to the letter? What if there was an actual effort at recovery? What would be different for you, if anything? Just something to think about.
Good on you for getting a second consultation and continuing to explore your options.
