I haven't had to deal with my wife moving out or even suggesting it, but I agree with Sandi and Zephyr. My approach would not involve being a nice guy. It's a fine line to walk, but you don't want to come off cold or mean, either.
If she's excited, throw water on her (rhetorically speaking of course). Now if she's nervous about her decision, point out that the "hard times" in this case are all her doing. You are not forcing her out, she is choosing her own path. To me it's important for her to realize that it is her decision to make, that any hardships are because of her decisions, and that you are not trying to control her (ie, you are detached).
That's just my $0.02, and I'm interested to hear what others have to say
