Got marry to immigrate now been one year and it's not working out what can I do

You do not provide sufficient information to respond intelligently.  Did the U.S. Citizen petition you?  Did you obtain a work permit?  Have you gotten your two-year green card?   If your spouse did not petition you, then if it's not working out, do what everyone else does - divorce. If you got married just for the green card, it's a fraud marriage and you both can get in trouble.
