Lots of good suggestions here. A lot of times with someone we want to work it out with, we just romanticize about the good times and forget the pain. Make sure when she does enter your mind, you make a point to remember the pain instead of the pleasure. Tell yourself this is part of the process of finding the right person and this isn't how you want to live in the long run (i.e. wondering who she's with every time she works late, is out with the girls, etc. Do you want to be at home taking care of the kids while she's out screwing around?) Trust, integrity, loyalty are things she either will never have or will never have for you.

To help keep her from getting in your mind, get rid of the things that remind you of her. Delete her from your phone, defriend in social media. Then, do stuff to keep your mind occupied. Take classes in something you've always wanted to do, think about what you need to do if you want to get another job... get out and do stuff.

Lastly, I am always amazed at the number of incredible women around when you're not actively looking. Do things for yourself and let the rest fall into place.

Best of luck!
