It's okay not to drag the D because at least you won't fight about it - give her what she needs and she'll give you what you need.
If you see her, just be nice and smile at her etc. Sound interested in her conversations, but be the first one to end the discussion.
Don't keep calling her and things like that, wait for her to call you. Also, look gorgeous (new clothes, haircut etc) and don't touch her, she might start realising what she's missing!
Get some new things in your life so she can see you are confident about 'moving on' without her and then she'll be like 'help! he doesn't need me.'
Reverse psychology - she might want you she thinks you don't want her. Also do some 180's on some of the issues that caused you to split up.
