Book on coping with a breakup and periodic thoughts about my ex-guy

A few weeks ago, I bought a book on how to cope with a breakup. I started reading the first chapter, but got busy with a couple of trips. The chapter that I did read put me at ease.

My problem isn't keeping busy. From being on vacation, and being out and about, to getting through work tasks, I don't have a chance to think about my ex-guy.

The problem occurs when I am not busy. My mind floats over to the loving moments that we had together, as well as the fact that I deserved better towards the end of our relationship. Before I go to bed, I think of him. When I am driving home and my commute is nothing to sneeze at, he pops up in my head. It just happens.

I didn't have this issue with my ex-hubby. The difference is that I loved my ex-guy. I fell out of love with the ex-hubby.

I am far from being over him. Baby steps. Gone is my mild anxiety about us not being a couple, which is a positive sign. 

This weekend, I hope to read more chapters out of this book. Perhaps my memories and thoughts of him will slowly subside.
