Alcoholic wife

I have been in the Army now for 15 years and married for the last 11 with 2 beautiful children age 3 and 10.
We both had the occasional bottle of wine when we first go married and had a good social life, but then for the last 6-7 years her drinking has slowly gotten worse. So bad that I was called back from Afghanistan because my wife had end stage liver failure. I'd spoken to my wife pretty much every day I was out there and she kept telling me she was fine. I got home for her doctor to tell me if she didn't improve within the next 24hrs he didn't think she would survive. A transplant was out of the question because her pancreas had become infected and released toxins into her blood and so was inoperable also because it was alcohol related they would have to wait 6 months of her being alcohol free.
She looked a mess when I was home on R&R she weighed close to 11 stone 6lb now she weighed 7 Stone 3lb and looked 9 months pregnant because her liver was not functioning and her muscles had been eaten away. With fantastic medical care she pulled through but was still on the transplant list and had to take god knows how many vitamin tablets daily. For 6 months she never drank. she had a scan on her liver and they told her she was extremely lucky her liver had recovered and had no scaring, no transplant was needed.
Now she promised me she would never drink again, she realized how stupid she was how she had hit rock bottom and she didn't want to lose me or the kids.
That lasted a couple more months until xmas and she decided to have a drink without me knowing she says to see if she could cope with it but obviously she couldn't and after finding bottles of vodka stashed and hidden around the house we had it out again and she didn't drink again until...
I went away for 4 months on exercise. Her mother came to stay and help her out and make sure she was ok. But after a month her mother lets me know she has been finding empty bottles again and my wife kicked my mother inlaw out of the house. I then had to get a friend of the family to come and stay with her to help with the kids and since then she has been drunk every time i have skyped or phoned. The kids are fine I speak to them everyday but I have had enough to many broken promises, I can't go away without worrying about the kids, if I'm going to get a phone call from the hospital and saying she is ill again or worse still dead.
I love her to bits but I can't go on like this anymore. But I know if I take the kids she will not be able to live with herself she would have nowhere to go or live (we are based in Germany she has no family in the UK and her Parents live overseas) I'm at a loss of what to do. I love her but can't be with her the way she is. Even if she got sober I don't know if i'd be able to trust her again.

slamb I'm sorry you're going through this, it's like you're being abused in a way. Are there local treatment options your wife can partake in?
