First, congratulations on your marriage! As far as waiting 2 months, that is not a long time in terms of processing PR applications, you should get used to it
Second - yes, it is very strange that you got engaged, applied as a single person, and then immediately got married after you applied. If you had waited a couple of weeks to apply after you got married, it would have been a much more "normal" application. Don't know what to tell you, but the fact that he's already in Canada may make it less of an issue.
