Rock. Here's the part that I'm not sure you understand: It's a two part process, going dark.
Part one: Stop communicating with her. Initiate nothing.
Part two (and most importantly): Stop obsessing about her. When your thoughts go in her direction, look at your feet, look up and around your space - is she physically there with you? If not, make a conscious decision to stop your wayward thoughts immediately.
Rock, the two things that I find most frustrating when trying to help you are your extreme co-dependance coupled with your stubborn refusal to stop all pursuit.
You need to re-train your mind, Rock. Plain and simple..
