Thanks for the clarification.
Sure it is possible to end your marriage now, and continue the process without your wife through a waiver of the joint filing requirement.
But you will have to inform the USCIS that this is happening. The USCIS will put your case on hold, and ask you to provide proof of the dissolved marriage and proof that at the time you got married, you did so in good faith.
This is the lawful and appropriate way to go about this process. And as long as you can show that the marriage was entered into in good faith, you should be able to go forward and get your 10-year card, without the assistance of your ex-wife.
