She's unsure of herself, this is normal. You have to wait for her to come to you which means keep your distance and let her make all the moves. Feelings take time to change and if you are too eager it turns her off. Just leave the ball in her court the whole time and don't make any moves towards her. Do not pursue.
She needs to miss you. You have a good start but you have to wait and it sucks and it will hurt. I have to do the same thing. I'm now trying to think of myself and things I want to do with my spare time instead of what my W is doing/thinking and it's not easy. This will be a long road and there's just no quick fix or answers.
