Will I loose the right to live in the country if I get divorced?

You appear to be in a dilemma because of uncertainty of what your husband will do. You can have the conditional basis of your residence status lifted in the event of a joint petition or if able to show that you have a bona fide marriage which has ended in divorce. I suggest that you submit the I-751 on time and explain your situation in writing with the application if you are still uncertain concerning his intentions and cannot have him sign. I also suggest that you begin working on a divorce action in the near future if it becomes apparent that he will not sign the petition. USCIS will take some months before reaching your petition and then will send a request for further evidence which will give you slightly less than three months from that date to submit a divorce decree. I note that whether in a joint petition or filing by yourself and claiming a bona fide marriage ending in divorce, you must submit documentation to prove the bona fide nature of your union.

There are certain situations that allow you to file a self-petition to removing the conditions on your permanent resident status.  Divorce will not automatically mean you cannot become a permanent resident.  If you can prove your marriage was entered into in good faith at the time you married, then subsequent divorce will be irrelevant.  Here's a link to more information about filing a self-petition: http://1.usa.gov/5BapUi
