Thanks, Mike. I'm glad someone understands.
It's not just that I am tired of his promises. It's also not that I don't want to support him. But the last time he drank, I was pushed to the point of shaking through the night with a can of mace in hand wondering what he was going to do to me as he went on a rampage downstairs.
This is something that people with non-abusive alcoholic partners fail to understand. Trust is not something that can be achieved immediately once a promise for sobriety is made, as one slip and I face the same nightmarish situation again. Or worse. He insists on my trust, just as several of the people who have posted replies to this thread have insisted, but it's really not that easy.
Then again, giving up completely and leaving someone you love and who claims his happiness depends on you staying isn't either. Therein lies the problem.
