You will need to be able to prove that this is a real marriage to be able to remove the conditions to your residence. You better start putting evidence together to prove this in case the things with your wife dont improve.
You need to get divorced first as a pre-condition to filing your waiver to obtain your permanent green card (10 year card) which is proved by documents showing you married your wife for bona fide reasons.
I agree with Mr. Sandoval. When you apply to lift the conditional residency, you will need to prove that the marriage was entered into legitimately. You should start documenting this in the event that you and your wife do not reconcile. Such evidence can include, but is not limited to, pictures, cards to one another and to each others' families, lease agreements and utility bills with both names on them, joint bank accounts ,credit cards and the like. I suggest contacting an immigration attorney when you are ready to apply to lift the conditional residency to help you with the process and to help you gather all documentary evidence that will be helpful in your particular case. Best of luck!
