need to be very very care for about the marriage GC right now.
IO may have a 1000 reasons to say you are not real marriage.
good choice for you:
GO BACK TO YOUR HOME WITH YOUR OTHER PART AND GET MARRY AT HOME LAND AND GET A MARRIAGE VISA BACK TO THE US.
OTHERWISE YOU MAY FIND A BIT DIFFICULTY TO RENEW YOUR GC IN THE FUTURE.
GOOD LUCK!
