My wife kept drinking at first, but one night the temptation was too great for me and I caved and ended up going on a week long bender. I didn't (and don't) think that's her fault, but honestly, it would have been easier on me if she hadn't been drinking while I was trying to quit. Since then, she's either been totally sober or a lot less obvious with the occasional drink. I think that the best thing to do is see if your significant other would be willing to stay dry for your first thirty days at least, since that seems to be the most difficult period.
