I miss her, and on some level I want her back, but I won't know how she's doing unless the lines of communication are reopened. If there's no chance of anything, I'm happy to move on, but I just want to start to know how she's feeling at this point and if she misses me at all too.
After reading that, it hardly sounds like it was a mutual decision to part ways.
Planning an elaborate scheme to figure out where her head / heart is, is just a waste of both of your time. So just use the K.I.S.S method.. Keep It Simple Stupid.
Just why did you break up, mutually or otherwise?
