I came to the USA with a fiancée visa , we got married and everything was great. now my husband wants a divorce

We were happy and even looking for a house . But My husband started to smoke too much weed lots addiction and problems we even went to a counselor . And now he decided he wants to divorce me. Right now I have the conditional permanent residence card ( expires in August 2017) I am from Belgium Now my question is. I finally got my life back together here ( moving isn't easy!) and I have a job that I really like ( I am a nurse here in Orgeon) Do you think I will be deported? I red that if I put a waiver in next time I have to apply for my green card if the marriage was in good faith and not fault of immigrant I red I can stay in the usa!? I do have proof of counselor and pre approval from the bank etc that we were together Do you think it will be alright? Or do you think I might consider to ask for a workpermit ? Thank you
