Is there a certain amount of time that it just becomes void through the court?

My husband filed for divorce out of the blue. It’s been over a month and nothing has been done. We have talked with his lawyer and made all the changes to the decree, but I still don't have the amended papers, no court date, and he doesn't want to talk about it. We have been dating, and trying to reconnect. I feel he regrets filing, but won’t say anything. If he isn't perusing anything, will it just fall off the system?
