Never got PR card

Yes, a landed PR is a landed PR. The PR card is not a condition of status. It is evidence of status. A PR without a PR card is still a PR.

There may be issues, however, such as identity for example, particularly if and when you go to obtain a Travel Document in order to travel to Canada. You still have your CoPR of course (keep it safe), the passport in which the original PR visa is affixed and cancelled (as of when you landed), so while you may have to go through some motions to satisfy the appropriate authority that you are indeed a PR of Canada, having done that, that should suffice.

In other words, there could be a bit of hassle involved, but you should indeed still have your PR status.

There are other potential issues of course. I do not know the context or other factors, so cannot really suggest what all the issues might be. However, depending on a variety of factors, the timing of living abroad immediately following your landing, for example, may raise a flag if your sponsor sponsored you while living abroad and thus made an affirmative representation (in the PR application) of an intent for the two of you to return to live in Canada, and the circumstances subsequently suggest that was a misrepresentation (no intent to come to Canada to live together). But even in a case like that, CIC or CBSA would have to commence an investigation and pursue a removal case based on inadmissibility for misrepresentation, and while this does happen, it seems it does not happen often.
