I hate to say it, but there's no social lubricant better than good 'ol booze. Why not take her out to a party, get a little lit with her, and then declare your love/hint subtly?

That's what I would do if you can. Spontaneity seems to be the best way for these things to evolve. Though the next day might be awkward, it will be YOUR responsibility to make sure she KNOWS that it wasn't just a drunken slip, that you meant what you said to her (if you can remember.) But acknowledge (on this day 2) that you aren't pushing her into anything. That you are glad you put it out there even though you had been waiting and are a little scared yourself.

I might avoid the word "love."
