Gosh, that's a tough one. Personally, I would stick it out. I think that it will get to her and she will start thinking more about the prospect of losing you indefinately. That's what I've been doing with mine. I've not called and when he's called, I answer, but on the 4th ring or after the machine picks up, or sometimes, I just call back. The conversations we've had have been a lot more productive, a lot more meaningful... I think that (as much as we don't like it) people need space to think about what is truely important to them. But you come to a point, which is where I am at, when is enough enough? I think it'll take more than a couple of conversations. If she's still bitter, your email probably won't do any good at this point.
