An immigrant doesn't need to stay married to successfully remove conditions. Sometimes the immigration issues get mixed up with the divorce issues. My best suggestion is that you get legal counsel on both the divorce and immigration issues, and make your decisions accordingly. The obligations on the I-864 will continue to exist, regardless, until death to you part (or your spouse leaves the US, becomes a US citizen or has worked 40 qualifying quarters for social security purposes).
