I am so sorry. Nothing to be afraid of though, he is far far away!
Personally, I agree with your lawyer. I would file first, just to be sure it's convenient for you.
Then I would sit back and let the cards fall a bit. Get yourself sorted. Get a job, a place to live, etc., etc. Put yourself first for a while and deal with him later.
Is he angry about something? Seems very spiteful. That's why I would give it time. Hopefully he'll come to his senses.
