That's quite a situation you have there. Although I don't really want to delve deep in emotions because as humans, it is one of our greatest weakness (a noteworthy mention would be sex, of course. Except for a few immune ones. ), it is interesting to see how we revolve and confuse ourselves with infatuation, love and crush (the sweet pure adoration). But this kind of situation made me remember about the old "Strong friendship is always reliable than a frail romantic one". But time is a great healer. So your silence might have some rewards. Should the one true "love" come, let her know. Who knows? She might share the same feelings. If not, then move along. If she's a real friend, she'd be open-minded about it. Sure it might be awkward but as cliche as it sounds "Honesty is the best Policy".
For now, keep dancing with time, enjoy life and keep the patience up. There's nothing more romantic than bumping your destined one in the park. Searching might be exciting, but spontaneous fate-directed encounters will draw that red string that binds us to our other half, and bring about that explosive romance and unending paradise. ^^
