Well this is my opinion, so take it with a grain of salt.
Don't move back in. At least not yet. I would suggest telling her that while you are not worried about your commitment to get things working, you definitely want to find out what went wrong the first time so that you have a happier and stronger marriage and life together than ever.
In order to do that, suggest C or a program like DB counseling or Retrouvaille. Whatever you choose, tell her that the two of you will be doing it together hand in hand. No blaming or fault. And that it takes two to get it to work and to get rid of the fears and insecurities.
If she balks at that, then tell her that you are not willing to move back in.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
