Do I have a chance?

I hate to ask fluther for relationship advice (I hate to ever ask for it), so I’ll try to keep this as brief as possible:
Basically: I’m near the point of dating this friend of mine, but she can’t make up her mind on whether or not she likes me or this other guy more.
I don’t know how much she’s thought about it, but I’m just wondering if its worth the continued pursuit. She told me about this almost a week ago, and while she refuses to see either of us while she’s figuring it out, our conversations seems to have stayed identical to before. She really likes me (she’s known for being quite prude, and we’ve kissed. Odd; I know, considering we still aren’t dating), and I really like her.
It’s also worth mentioning: the other guy is one of her best friends and has been for a few years.
