Breathe. If he's retained a lawyer, then it's time for you to be seeking legal representation or at the very least speaking to a lawyer to see what your options are and what you are entitled to. He could very well be saying things about a lawyer to shake you up...until you actually receive something in hand, then I wouldn't freak out.
Definitely start shopping around for legal advice today. Some lawyer's offer a "first" consultation for free. Start looking around and setting up appointments today. Don't put this off. There is nothing wrong in educating yourself on the legalities of separation/divorce...just don't share w/your h what you learn.
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.
