My wife recently decided we should get a divorce. Please help? Details inside?

We already had one miscarriage and on feb 8 2010 we found out we had a healthy 6 week old baby that she is pregnant with. Two days later she told me she wants a divorce. I am tottally heartbroken. I want to be back with her and I think I have messed up by pretty much begging her to reconsider for about a week. I read that I should just give her time to think, heal and get through some things. I am moving 12 hours away from her with nothing but my cloths. Just recently had an accident and totaled my car. I plan on just not taking any calls or having any communication with her. It is really hard because just talking to her comforts me. I am hurting bad and not sure I can handle not talking with her. Should I give her time and space alone without talking to her? What can I do to help with and dealing with this pain? Thank you for the advice.
