Why Couldn't I Get Over Him?

After we divorced, the time I spent away from him was good for me. I learned how to live a "new" life. I learned how to settle down a bit. I didn't have to wait until he was in the shower to check his cell phone calls that had come in. I didn't have to go running outside to check inside of his work truck to see if there was loads of cash stashed away in his secret hiding places. I learned how to relax and take it easy some. So, why after having such a much more life of "ease" did I get back with him? I wasn't having to worry about his cheating anymore. I was free. I think that my problem was I left so quickly, that I didn't really have time to work through my problems with him. I didn't face what I had to face with him, leaving me only to wonder about what was going on while we were apart, when I shouldn't have even worried. I loved him and I really did have a hard time getting over him, even though he hurt me so much. I really can't explain why.
