Dealing with Intrusive Thoughts about an ex?

Humans are plagued when it comes to memories. There are some good books. One is by Dr. Wayne Dyer, 'Your Erroneous Zones" and then there's Zig Ziglar's "See You at the Top." The first one shows you how you tell yourself you are unhappy, sad, etc. The second will help you learn how to be motivated. Get out there girl and have some fun.
