How to Stop I-751 Removal of Conditions

[maxer]

I have petitioned my wife to come here on a fiancé visa and she has obtained her 2 year conditional GC. Our marriage has gone from bad to worse and I believe she has married me just so she could send money to her family back home. I could try to have the marriage annulled since she has refused to consummate it. I am afraid, however, that she might try to file an I-751 with a waiver to obtain her 10 year GC. Then she could move in with her relatives and demand I support her for the next 10+ years based on the I-864 the government required me to sign.

I don’t feel that my life and financial future should be ruined because I was duped into marrying this greedy person. How can I best prevent her from getting a 10 year GC? Should I get an annulment and try to convince the USCIS that the marriage was not valid? Should I stay married for another year until her GC is set to expire and then do everything to not cooperate with the I-751 process so she has to go back home?

Please help me get out of this nightmare!

If you don't cooperate with her in getting the conditions removed in conditional GC, she will automatically lose it.
