Where do I go from here?

After struggling to save my marriage for almost a year, things are finally going down the drain.  In the last week I have moved out of my house and into an apartment and my failing marriage has finally finished what it has started. 
My wife no longer wants to be open with me...  She wants her own private bank account, her own cell phone on her own plan... She says she doesn't want to feel like I am her father.  Unfortunately, after she had an emotional affair with another man for nine months, how can I ever rebuild trust if she won't be open with me?  I told her those things would come in time, but she said she just can't deal with it anymore, so I guess that seals things.
I don't know what to do...  I've given everything to my marriage, and I am left with very little.  Now I have to go about trying to rebuild my life, and I have no idea where to start.  My life has been in turmoil for a year, and instead of getting better it seems to be getting worse.  What started with an affair has now turned into her telling me she wants a divorce.  The separation papers are drafted, the things divided, and all that is left to do now is to sign and file I guess.
I never wanted this.
