If you try to land and don't give her address, they will definitely ask why. They may call her and ask if she still wants you to immigrate or if you are already separated. It is likely that you would be sent back and your visa cancelled. It will however also get her in trouble if you provide the divorce papers saying you were already divorced when she landed. If she used funds in your name, she can no longer say it was an oversight on her part not telling them because she had a motive to lie.
Edit: I just read your last post saying you were present at this interview. If you were sitting there while already divorced and not stopping her when she is lying, you are guilty of the lie too. In that case, it is better that you let your PR visa expire, apply on your own and never tell immigration about the lie.
If you never plan to tell immigration about the lie, you could also force your wife to let you land by sending her an email or communicating through her relatives that if she does not tell you her address so you can also land, you will let immigration know that she lied and she will lose her PR.
