Uh, well...at the risk of sounding like Julia Roberts' sidekick in said movie...you should talk to her. And it's the hardest thing to do, really, but its the only way you're ever going to know if there's anything there worth risking your heart over.
Invite her over, have dinner. Talk. Don't snark. DON'T RILE HER UP. Just talk to her, like you'd talk to...Jo. Or...uh...someone who's pants you're not trying to get into. Long after the two of you stop being pretty, you'll still have to do something with each other--so see if you can at least have a non-sexual conversation.
Christ, I should have my own talk show. *facepalm* I need to go burn some meat on the grill and drink too many beers.
