If you have your 2-year conditional permanent residence and you can prove up the bona fides of the marriage, then you can get your conditions removed without assistance from your wife. To file the I-751, you need to be divorced and have strong evidence of cohabitation and co-mingling of funds. You should get as much of this evidence as possible now, as once you file for divorce, you may no longer have access to joint documents and photos, etc.
