I agree with awest. I would not pursue your X. She has to see your changes for a pretty good while before she will let herself believe you have changed. She IS watching everything you do, whether you realize it or not.
Remember, time is on your side, even though it feels like your enemy. Patience, patience, then more patience.
One of the best illustrations someone gave me here about where you are right now is to imaging you are trying to convince a frightened animal to eat from you hand. You do that by very subtle and SLOW movements. Anything quick or abrupt, and the animal gets scared and runs off into the forest.
Here's another story (called the Picnic Analogy)that helps show what you are trying to do (and I copied this from someone esle):
THE PICNIC ANALOGY
Imagine that the WAS is inside an impenetrable castle. WAS is deep inside the castle walls and has no desire to see the outside world. WAS has his/her own world right there inside those cold, stone walls.
Then there's you. You're sitting on the other side of the moat (drawbridge is up, btw). You've got a nice blanket laid out on the cool, green grass, and you're enjoying yourself by having a wonderful picnic all alone. You're absolutely content with this, and aren't even concerned with the castle and the WAS within (in fact, you've got your back to it).
Eventually, WAS gets a little curious about the what's going on outside the castle, and decides to take a peak over the walls. WAS sees you, just sitting there enjoying yourself. He/She is surprised, because previously you had been throwing rocks at the castle, singing and dancing in hopes of getting their attention. WAS is wondering what you're up to, and why you're so content. After a while, WAS decides to lower the drawbridge and join you at your picnic. WAS sits down, and you just act as if -- you're happy, confident, etc. Suddenly, WAS realized where he/she is and what he/she is doing, and it scares the hell out him/her. WAS jumps up and dashes back to the castle for no apparent reason. You however, didn't even budge or flinch. WAS peeks back out to see what you're doing, and notices that you're still sitting in the same place, enjoying yourself without concern. Again, WAS is surprised, and eventually comes out again. This time WAS stays a little longer, but again gets spooked and runs back. However, you're still not deterred from enjoying your picnic. The WAS's visits begin to happen more and more, and they last longer and longer. Once he/she realizes that there is no risk for him/her (i.e. that you won't bring up the R, pursue her, get angry, become needy, etc), WAS begins to reflect on things, and begins questioning his/her choice to go to the castle. In time, WAS decides to bring up the R, and this is when you can discuss it with him/her because WAS is ready and has initiated the talk.
THIS is why it is important to avoid pursuing, because it gives the WAS the opportunity to miss you, reflect, see your changes and strength, etc. So, the next time me or anyone else tells you to just enjoy your picnic, you'll know what it means. This is a term that we used a lot this summer, but it kind of went away. I think it describes the pursuit dynamic perfectly. Don't chase the WAS back into the castle and hold him/her captive by standing outside the walls and trying to get his/her attention. As long as this is the case, it is likely that they'd rather starve themselves in their castle than come out.
