something happened in her brain... and she reverted to run mode...

perhaps she's given you a clue...

"I don't feel anything for you."

Empty? Really? Or has her "feel" simply been transfered or stuffed...?

Are you still doing the things that she "misses"? If not, could / would you get back to that stuff? Back to the parts of the man she misses? 'cause there's certainly some feeling "there"...
