What should I do about my lost love?

Hi my name is Doug, and I'm known as Stevey225 in the online multiplayer game runescape. A couple years ago I feel in love with this girl online, her name was Chelsea, A.K.A The Peach, in game. We did everything together such as follow eachother around all day at edge bank. Everything was well and good until all my friends started talking to her. She was so beautiful, he pixelated sent shivers down my spine. I got so pissed off with all the guys she was talking to, I told her last week to please stop typing to them. She doesn't want to talk to me ever since. I know I was a little bit demanding but I love her and I one day want to get married with her in Varock Palace with all my friends cheering me on! But alas, that day will never come true =( she hates me now. What can I do to get her to love me again?
