There are 2 ways for your

1. like many people sugggested here, fighting in the court for your interest. treating your hu*****and as a bustard. Maybe finally, you can get your GC, even get some money from your hu*****and. Maybe you need to fight like a *****. Then you may get what some people called you future life---GC + money + forever scar in your mind + dark image of life and world as those people hold who suggested you to this.

2. Let it goes. Give yourself a peaceful and broad mind. Try to save your hu*****and soul. See if you still have love between. If not, endup this marriage peacefully. Make your life bright if you still can keep friendship, and have a nice memory of your past life. Then you can start your new life without any burden from past. You still can have a bright future.

Which way you really lost, and really gain? you can select.
