Unfortunately there's no way to easily or urgently check if you PR is still valid. If your husband reported the fact that your relationship fell apart to CIC - it's possible your PR status has been canceled. Also quite possible your PR status is still valid.
One way to check would be to simply travel to Canada as a PR and see what happens at the border.
You could also try applying for a PR Travel Document from your home country and see if it's issued (if it's issued, you're still a PR).
