Hi, I understand that in Spanish we dont use -ing words the same as in English however I have a question regarding using them for past.

For example, I would use estoy esperando to say im waiting, if at that very second I am doing some waiting. However I have seen a few occasions written where it says "Estaba esperando" to mean I was waiting.

If we only use the gerund to say things we are currently in the middle of doing, why is it ok to use estaba to refer to something we were doing?

Or am I completely wrong?!
