By the way I do agree with Steve that you should just not go at all. My suggestions fall under the "if you DO go, then do this" category. Right now you can't "nice" her back. You also can't "mean" her back. You can't get her back at all, not until SHE has a change of heart. Which if it comes at all, will be WAY down the road. The best thing you can do to help things along right now is.... nothing. Time and space. Leave her alone. Keep contact to the bare essentials. Be a ghost. Not cold, rude and indifferent, just... not there.
