What should I do to get my ex to go back out with me (get us back together)?

Her facebook status makes it look like she's hurting and it's been about a week since the breakup. Problem is, I promised her I wouldn't contact her for at least a month. So what do I or do I do anything at all? She was the one who broke up with me but I was really amazing during the whole thing (honestly) but now I'm unsure of how to proceed. Let her stew some more, contact her, be mean (not my favorite), or what?
