I don't think your experience here is weird - just seems like you had a good environment for practicing a bit with your wife, which I think is more important than any other aspect of the learning methodology. Now, nitpickers might argue that "better" methods would have achieved much more in less time, but eh.

Try to force some more exchanges with your wife. Make a day of the week the day you only speak her language (for at least a few hours, but don't give up from the frustration when vocabulary runs short - keep it going even if you need to point and sign).

Doubles as a silly/fun couples activity.
