It depends on how solid her relationship w/ Harry is, and Harry's wishes. Does Harry want to marry her, or are they in a place where they might commit permanently to each other? If so, then no. Ginny waited five years for Harry, if he says he's coming back and she'll always have him, then she'll wait till the end of time.
It would be a Post-Hogwarts fic (like a year or two Ginny is out of school), she is dating Harry, the war is over, and everything, but Harry's going to be away for a few years (2 1/2 - 3 at the most), because of Quidditch, and Ginny knows she isn't going to be able to see him for a few years, because he's away at some Quidditch camp or something (yet to be decided).
So, do you think Ginny is the type of person who would break it off with Harry, so she could, you know, explore life and try and find who she 'apparantly is', and like date other people, you think?
Of course you don't want her to mope. I see Ginny using such a time to just live life normally, working, finding her place in the adult world, and writing Harry often. Women do it when their men go to war; couples do it when they live in different cities. Why can't Ginny and Harry?
I think this thread has already established (I haven't read the whole thing, just skimmed) that Ginny isn't the type of person who would wait around for someone, like Harry, and pining over him, thinking of him day and night, depressed, when he's out, sort of having fun. It would make more sense of her to just try and live life, doing usual things like dating, having fun, hanging out, and not worrying about Harry 24/7. You could call it, trying to 'find herself', and who she is, without Harry in her life. Make sense?
