Since no one else has mentioned this aspect of it, I just have to say that I would think long and hard about staying attached to someone who drinks enough to pass out... even rarely. It indicates a serious problem that will probably require professional help before it gets better.
If he's willing to get help, and you're willing to help him work through it... that's great. But if he's not... you could be setting yourself up for a lifetime of misery.
