Welcome to Hell. I'm here to greet you and share that your answer lies in Alanon. Go as often as you can for as long as you can, and read many, many posts here. She is going to destroy your credit, your retirement, and you if you let her. Not because she is evil, but because alcoholism is evil.
She's no longer capable of making good decisions or caring about anybody else. She is no longer the woman she was, and she never will be again even if she finds sobriety. Your old life with her is over forever. But, if she finds sobriety, there may be a good life with her again. The problem is that she is a long way from doing that right now and IMHO you can do only one thing about it-- work on yourself in Alanon.
Separately, please consider selling all but one of your vehicles and then making sure you have the only way to start that rig. She will kill somebody, herself, or both-- it's just a matter of time while she's drinking.
Good luck to you Sir, and if you care about her as much as you say you do you will attend at least six Alanon meetings before giving up.
Take care,
Cyranoak
