<human>: I think I need to break up with my long term girlfriend, but I don't think I can or should. 

Backstory: My girlfriend and I have been dating for a collective 7 years (on and off between the ages of 15-22). This past summer I kept feeling like I should break up with her, but I didn't, then I moved away to college (800km away) and I didn't/haven't missed her at all. We rarely talk, and im perfectly fine with this. I started meeting new people at college. I talked to one of my newest friends about my relationship, and she said that maybe I should just end it. So for holidays I went back home, and told myself I would have to talk to her, I wanted to break up. But she insisted that I should actually try to keep us together, since she sees us getting married, having children together etc. I told her fine I would try. But, ever since I got back to college, I haven't wanted to, I just don't know If I want to be with her. Now here is the twist. She left Canada for a job in Australia, and I wont see her for 6 months. I don't want to be a jerk and break up with her while shes halfway across the world, because I couldn't end it to her face. Plus theres a girl here that I have begun to get along with quite well, and I feel happier with her, then my girlfriend, but I don't know if its just like a "honeymoon phase" even though we aren't dating, but like, shes someone new and awesome. I just have no idea what to do, and if I should break up with her I have no idea how to do it. but I just don't feel happy thinking about her at all.

anymore questions feel free to ask, thank you
