As long as you have proof that you live with your Canadian citizen spouse, you maintain the PR requirement and are still a PR while living outside Canada. You don't have to end your PR status. Since you are still PR, she cannot sponsor you.
Thank you for your prompt answer!
the date I left Canada last time with my wife was after the expiry date of PR card, and I didn't renew it. If I want to return to Canada again with my wife, is it the only way to get a travelling document? or can I use the expired PR card?
