Powerprincess, wow, chill out. No one is going to listen to you if you give outburst like that. Guys tend to blow off women who react like that as just being silly and emotional, and won't take you seriously. Calm down, and explain your side with detail, without getting angry and you'll get alot farther.
Shoot me up, sounds like a head trip. Anyway, for this one I don't have any great insightful advice. You've got a good thing going, don't blow it. Maybe she'll grow on you. If you tell her you don't love her, and she is actually interested in anything more than a sex with you, she'll definately be hurt, and will probably tell you to "hit the road...asshole". You need to find out what her feelings really are, and decide what you really want. If you can't just fuck her without feeling bad about it, you know you don't want a relationship with her, and it turns out she really does love you, you might want to cut her loose. That's about the best I can do on this one.
