My guess is she's not coming back any time soon... but over the coming years, if you have a comfortable friendship, things might just click two to three years from now.
You've said you don't plan on dating (but don't tell her that, you should be a little mysterious.... it wouldn't hurt if she thought every single woman at your church was on pins and needles waiting for you to be divorced ;-) ), so you really have nothing to lose by leaving the door open a crack. Don't YOU open it!!! If she wants to come back SHE will. You really lose nothing here, and quite honestly, you have a lot of self-discovery and growth to gain regardless of what happens.
There is no arriving, ever. It is all a continual becoming.
