The point made above is the most logical explanation. Your lawyer has most likely filed whatever needs to be filed. That has some sort of deadline which is forthcoming. Until then, nothing else can be done, nor need be done. He or she probably gave you some idea of how the case would progress, and that's likely what is going down. You may think you should hear from the lawyer, but in all likelihood, you will only ever get to speak to his assistant. That's how it works sometimes.
