Welcome Scratchnhead. I'm so glad you found us and so very sorry for the reason. This must be over-the-top painful for you.
The best thing you can do in this situation is to take care of yourself and learn everything you can about having a relationship with an alcoholic. The stickies at the top are a good place to start. You also might try an Alanon meeting although they don't fit everyone.
Let us know how you are. There are many people here who have been through the wringer with alcoholics.
