I am CRAZY for this guy I met online, and I think I'm in love, LOVE!What do i do?

I never wanted to fall in love. Anyways, I met him online and we talked a lot, we got to know eachother. Then he dropped the bomb on me. He asked if i like liked him. I said "i dont know." Dont give me that look, i had said to myself years earlier that i would never fall in love, and that was the side of me that was talking. He got really pissed off. He left, then a little later came back and said that he was sorry for leaving me, i said it was okay. I kept talking to him, then i had to get off of the computer, i said i would be back in half an hour, i couldnt wait for his response, because my sister is very impatient. In half an our, i got back on, but he was gone. I waited for him and looked everywhere for him. In the weeks that followed, i always looked for him. Soon I was drawing him, and me, and hearts with our online anitials. I argued with myself. The side that wanted him so very much, and the side that said i would never fall in love. The side that needs him now, won. Online i always waited at his place and checked over and over to see if he was online. He came back, but broke my heart. When I talked to him, we talked for a while. I went to his online house, all we're allowed to do is sit and stand and fly. Then i said he remined me of a song called smile, because he makes me smile. Then i said stuff about how i would be blushing, if i could, because i never have. He stopped talking to me and left somewhere. I went to him, then left as fast as i could. He was with some girl. I asked if they were dating, he said yes he's taken. I said finally like i was teasing, then left. i became friends with his girl, once i found out who she was, he doesnt know. Im friends with her, and i think they broke up. I wish for him to love me and for him to say so. IM IN LOVE.
