I know that this is long but I need relationship help big time with this girl; any help would be fantastic?

So basically this entire issue has absorbed my life and I have tried everything to try to put it to rest but just can't do it. It started out by me and this girl sitting next to each other in bio class. She has the greatest personality out of any girl I have meet and she is almost a carbon copy of me. After getting to know her fairly well I asked her to go with me to the Mid Winter dance at my school. She went with me and I swear to God that was the night that I fell in love with her; she looked like an angel that fell out of heaven. Long blond hair, deep blue eyes, burgundy dress, and a pearl neck lass; I could have died right there. I never thought that I would ever take a girl like that to a dance in my life. So during the dance it was a slow song and I had my hands behind her back, looked into those deep blue eyes as far as I could and I said "You know, I have never seen eye's as pretty as yours..." and I tried to say it in the sweetest and most sincere voice that I could. She blushed up immediately, smiled, looked away for a second and then came right back and meat my eyes. We stared into each other for about 10 seconds and looked away. I'm saying this just to confirm to everyone reading this that she at one point did like me. Then that following valentines day weekend we went on our first date together. It was a tiny bit awkward for me at least, but thats probably just because I am not exactly confident in my abilities with the ladies and I have the most beautiful girl that I have ever seen in my entire life sitting across the table from me. The entire thing went great and we both I think had a really fun time. But then we didn't talk or go out for about a month (at this point we switched seats in bio). Im not exactly sure why; we just didn't. Then one night I get a call from her. She says basically that she had a fun time on our last date (score!), but just wants to get the entire silence thing out of the way. Also that she thinks that the last date might have been a little awkward because it was just the two of us out for dinner and then a movie on our first date, and so she thinks it would be a good idea if we made plans to go out on a double date type thing. I said that I agree that that would be a terrific idea and that maybe this weekend we could go bowling with some friends. She said sure that sounds great....we haven't really talked since. We just never called each other or anything; just complete stop of communication. This happened almost 2 months ago, and we still haven't really talked since. Also I forgot to mention this, but she knows that I REALLY like her; I gave her a really deep and sorta heavy love note before our first date so she knows that I one point I liked her a LOTT. And to be honest, I still like and love her just as much; in fact I would die for her. And this is no puppy love situation, I have never had a gf before her, and was never really into the whole dating thing. I am also a World Champion in Taekwondo, and I am trained to forget about emotions, and I just can't; Ive never felt anything like this before in my entire life. And that is basically why I am writing this in the first place; to be honest the entire situation is messing with my head and I am not in the right place when I train. In other words my head is no longer in it because I cant stop thinking about her. And at first I did think that maybe this is a puppy love situation and that if I just left it alone it would all just go away....hasn't exactly happened yet. So after all of this, my question is how should I go up to her and approach her after this long period of time and how should I do it? What should I say to her once I do go up to her and begin to talk to her? Also anything else that you could think of would be absolutely fantastic and thank you so much for your time reading this and your help.
