If worst comes to worst honesty is always the best policy, and you honestly like someone else. Social skills tip #1 with honesty is that, in choosing to follow this specific route, you need to let her down easy. Tell her you're flattered she would want to spend time with you, but you just don't reciprocate those feelings and have feelings for someone else. Don't give anything away, too, that she could go crazy over (i.e. the girls name, who this peach then stalks and badgers on Facebook or some other social networking site).

But yeah. GL Tobias.
