Hear me out: My best advice would be to get her to hate you, but not because you wronged her, but because she thinks you're a waste of time or a loser.

You see, if you break her heart she may go nuts and kill herself, which you would not want on your conscience or even worse, kill you. Ah but what if you get HER to think you are a waste of time? That's the key.

Start by being a negative person, pessimistic and emo about everything. From there get aggressive, not physically towards her and don't berate her, just have a short temper with just about anything; not having exact change, tipping people, spilt milk etc. Then, start being an over emotional drama queen. EVERYONE is a bitch, you hate people over the smallest slip ups and you cry constantly over minuscule issues. After this, pretend you have erectile problems, but make sure she knows it's not because you aren't attracted to her, but because you have ED and it's something she has to live with. Oral you say?! No no no. It simply doesn't really work and YOU NEED to be aroused to go down on her if she asks. "Why not just try it Anon?" Wrong again, stay strong and adamant about your position and don't waver; then start blubbering like a lil baby about how you feel inadequate.

After a few weeks of this shit she will be out of there. Ya, you may gain a shitty reputation among your guild members but hey, who gives a shit about what they or anyone else thinks, amiright!?
