Umm, how about some personal contact first? Like go talk to her, invite her out, stuff like that? I mean, sorry if i sound blunt or anything, but how do you expect to approach a girl when a) you send someone else to do the talking b) you continue NOT talking to her in person by sending emails?
If you are really in love with her, trust me; go talk to her. That's what she would want; you are not making a very good impression by "avoiding" her. Simple as that. Even if she turns you down (which i sincerely NOT hope so), you will know that you tried and you will have a piece of mind. Living with a big "what if" in your head is not the best of things, especially since you fall in love for the first time.
