How do I get her off WoW?

I was close friends with a girl. We both played the same MMO Ragnarok Online, and we were playing that together, on the same private server, until around 2-3 months ago.

Then I started going all lovey-dovey over her, and started making her feel uncomfortable around me because I would go emo over everything she said. She finally told me it’s best if we were just friends.

I was afraid that she would not play RO anymore. I was right - and my worst fear was confirmed. She now wants to play WoW. As friends before all this drama started, we had shared our good times all over RO, and were esentially the dream team. She wants to forget all of that and play WoW. I would have followed her except 1) I didn’t want to have the title of “stalker” added to the list, 2) She chose WoW Retail, and had her mom pay for her, my parents don’t even know I play games so I’m dead there and 3) I just didn’t want to if I was just playing WoW to be with her.

Now, as a friend, I want to know if there is anything I can do to get her off WoW. She has already completely forgotten about Ragnarok Online, doesn’t talk to me anymore on chat unless I talk to her first, and rarely in IRL.

Despite the fact she pretty much ditched me, I still care for her. And she has terrible grades, and on top of that, she saw fit to forget about everything. I just want her to get off WoW - anyone have suggestions in general for getting people off WoW?
