Oh man, do I ever understand what you are going through. Seizures, breathalyzers, promises. I am just on the other side, having left my husband about 6 months ago. It was a long, grueling process. Now we share kids together and I get to second guess his attempts at sobriety from afar. Not fun. But so much better than being entangled in that mess. Yes, it can feel terrible to walk away from so much past and so much potential. But when the present speaks so loudly and clearly, I really couldn't ignore it any longer. And to answer your question, No, I would never knowingly get into a relationship with an alcoholic ever again. It's too much of a beast.
