Okay, since you asked so nicely.
The housing situation is temporary - you said for one year. Even if you didn't say that, my guess is you didn't plan on spending the rest of your life living with the same 7 people.
Your situation with the girl is...well, we don't know, do we?
My suggestion to you is this: don't let it find its way into the "we'll never know" category. Nothing in this world -
nothing - sucks harder than regret.
Almost nobody ever says, "Man, I wish twenty years ago I had never tried to go out with what's-her-name. I mean, we went out twice and she ended up moving out six months later!" Plenty of people say, "Man, I should have asked her out - it might have been good for only a few dates, but now I'll never know."
What's the best that could happen? You could date for a few years or more, maybe even get married. Sounds great to me, too - and I'm not being facetious. The worst that could happen? She shoots you down, or you go out on one or two bad dates, live together with a modest amount of discomfort around each other (after all, there are eight of you; pretty easy for the two of you to find others to occupy yourselves with to minimize the awkwardness, if it really came to that), or one of you moves out - but no biggie there, since you're all moving out in a year anyway, right?
Nothing ventured, nothing gained. Now, I'll apologize for not going into this level of detail earlier, but when I previously intimated that the answer was obvious, this is what I was thinking. If I wrongly assumed that you and I were on the same page with this, I'll eat my crow and move on. But don't fall victim to the regret of wondering what might have been; make your move and see what happens.
