I agree with givelove. And I do think there's a chance that in days, weeks or months he is going to come back full of "remorse" (not really) and "apology" (not true) and ask you to give him another chance. Why do I think this? Because alcoholics stay miserable, wherever they are and whoever they're with. And they think if they just change the place or the person, things will be great again. So they often go back to former partners, their heads filled with crazy illusions that that will solve their problems.
Take good care of yourself.
