Separations are hard, so it's best to keep oneself occupied.
Personally I did small projects around the house, cleaned up took up hobbies, hanged out with friends, but most importantly let W contact me. During this time your W does not want you to chase after her groveling. So don't.
Think of it as your chance to reclaim your manhood. Do those things you always wanted to do. Eventually when you do have contact you will be much more confident and she'll tell something is up.
Besides which is better:
"What have you been up to?"
"Crying and missing you...."
Or
"what have you been up to?"
"went skydiving"
"what?!"
Also use Facebook as your propaganda tool, post pictures of your new adventures, be more social and such.
Most importantly when she comes to you stand up for yourself. Don't be a jerk or argue, just stand up for yourself.
If you have mutual friends, be alpha in front of them, word will get to her. (as in charming, confident, and funny)
