Separated from spouse, but only have conditional green card

My husband has left me for another woman recently. I received my conditional green card in June 2007.
My husband says he will still sign the paperwork in 2 years to take off the conditional status, however, I rather apply to remove the conditions myself, which I hear is possible.
What kind of information do I need to submit under my situation. Or would you advise me to stay married, and let my husband just sign the paperwork next year to remove my conditional status? I do have photos, cards, and text messages to show he's cheated if any of that will help

Get immigration counsel involved but you can still stay as long as the marriage was real at the time you married.

But Immigration will examine that issue closely.
