The case not being filed could mean one of three things: either the lawyer hasn't had the time to file or he/she is out of town and will file when they get paid or have the time to file; and/ or your wife has requested that it be held in the lawyer's office until further notice. Whatever the reason, continue moving forward.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
