I am a 21 yr old female who, has been hurt by plenty of guys. I think, coming from a female's point of view, that the fact you've talked to her about this means that you respect her and care about her more than the other guys that have been in her past. I know that with my past, the guys who hurt me lied to me, led me on, slept with others behind my back etc. Each time I was hurt, it was always to do with the guy being selfish, and the situation I was in with the guy at that time was always grey; never black and white. So you can see the certain pattern: I was hurt most by the guys who lied and were selfish and didn't think about how I felt. The fact that you're moving away isn't the "problem". The "problem" is that you're worried about hurting this girl. This is a very unselfish and respectful way of telling her the truth and realising the situation, including realising how she would feel. The fact she's said that she would be able to try and be apart also shows that she is aware you are taking her feelings into consideration. I don't think she is going to be hurt about you moving (it will be sad, don't get me wrong!) but she will be hurt if you hide things, or don't take her feelings into consideration and think about her.

Hope my female reply helps!
