Can I get my CPR removed without my abusive husband knowing?

Although not completely clear from your question, I presume that you already have succeeded in attaining Conditional Resident status through a marriage-based adjustment of status application, that you are contemplating separation and divorce, and that you want to know whether you may succeed in a Petition to Remove Conditions without your husband's participation. If my presumption is correct, then note that generally upon becoming divorced a foreign national spouse may succeed in a Petition to Remove Conditions with a request for a waiver of the usual requirement that the U.S. citizen spouse participate in a jointly filed Petition. To succeed in that case, it would be necessary to have a strong set of documentary evidence showing that you and your husband lived together in a bona fide marriage notwithstanding that it ultimately ended in divorce. There are many other details of importance, including timing of the filing of such an application, for which there really is no substitute for consulting with an immigration attorney who, after learning all of the relevant information, could advise about eligibilities, options and strategies to attain your goals, and who then could offer legal representation in the often complex application process.
