Cain, to be honest?
I don't think you'll be getting back together, unless you're both secretly staying mutual to each other.
With an indefinite time line to this "break", and you're disposition to refrain from pressuring her any, (pressure isn't always a bad thing), I think what will end up happening is you'll both simply grow apart, especially considering you live so far away from each other and you both have your own life agenda to follow.
However, should this actually be the break up (without yous knowin' it yet), it'll be a shit load less painful this way, than goin' cold turkey.
I tried to quit Amy cold turkey because she wasn't gonna give us a chance. I blubbered like a little baby, but she still broke first. So I won that round.
I'm not going to wish luck to this relationship because I have little faith in it, however, I do wish luck to you, your good decision making, and your future.
