In theory, you can report this to immigration but be careful not to incriminate yourself - they may see you as a guilty party to the marriage fraud as well, since you willingly entered into a marriage knowing that the motives may not have been solely for love and companionship (IF I understand your question correctly - it is ambiguous because on the one hand you state "I thought it was for real" but then talk about being blackmail and pressure. You were under no obligation to marry someone and could have sought protection from the abuse and duress, especially as a citizen who is likely more aware of the laws and more sophisticated in organizing assistance than most non-documents individuals would be. Finally, I am not sure as to the motives you have for reporting it now. If it is for revenge or because he was not fair to you, I would suggest you move on with your life and try to make better choices in the future with your partners. Use it as a learning experience. I strongly believe in karma and that his time to pay back will come, at which point you can smile - if you still care either way, at that point. Talk to a counselor and perhaps an immigration attorney to get more perspectives as I am sure you may not like what I have advised you here, but it is my honest advice taking into consideration what is ultimately best for YOU as well.
This advice does not form an attorney-client relationship and is merely informative. It should not by itself be relied upon to address a legal concern.
He must demonstrate that the marriage was bona fide when it was entered into. You can report him to ICE, but you will have to show more than that the marriage did not work out after two years.
Mr. Shusterman's (former INS Trial Attorney, 1976-82) response to your question is general in nature, as not all the facts are known to him. You should retain an attorney experienced in immigration law to review all the facts in your case in order to receive advice specific to your case. Mr. Shusterman's statement above does not create an attorney/client relationship.
I agree with Ms. Brost. Reporting this may cause you to be investigated as well. I would encourage you to discuss the details of this matter privately with an immigration attorney.

They will likely investigate and ask him about your allegations and if he cannot rebut them then he will not be able to remove his conditions but be careful not to incriminate yourself as if they think you knowingly enter into marriage fraud that could cause some issues for you.
