Hi zrx, I am sorry to hear all of what you have gone through and are going through.
I recommend you get a copy of "codependent no more" by Melody Beatty. Great book.
Your post reminded me of this article:
Addiction, Lies and Relationships
Excerpt:
Addiction protects and augments itself by means of a bodyguard of lies, distortions and evasions that taken together amount to a full scale assault upon consensual reality. Because addiction involves irrational and unhealthy thinking and behavior, its presence results in cognitive dissonance both within the addict himself and in the intersubjective realm of ongoing personal relationships.
In order for the addiction to continue it requires an increasingly idiosyncratic private reality subject to the needs of the addictive process and indifferent or even actively hostile to the healthy needs of the addict and those around him. This encroachment of the fundamentally autistic, even insane private reality of the addict upon the reality of his family and close associates inevitably causes friction and churn as natural corrective feedback mechanisms come into usually futile play in an effort to restore the addict's increasingly deviant reality towards normal. Questions, discussions, presentations of facts, confrontations, pleas, threats, ultimatums and arguments are characteristic of this process, which in more fortunate and less severe cases of addiction may sometimes actually succeed in its aim of arresting the addiction. But in the more serious or advanced cases all such human counter-attacks upon the addiction, even, indeed especially when they come from those closest and dearest to the addict, fall upon deaf ears and a hardened heart. The addict's obsession-driven, monomaniacal private reality prevents him from being able to hear and assimilate anything that would if acknowledged pose a threat to the continuance of his addiction.
You cannot control her drinking
You cannot cure her
You did not cause this
You could not have prevented this
You can only control your life and your choices... you deserve to have your needs met.
