I'm just getting caught up on your sitch... it sucks. Big hugs for you.
Protect yourself financially. As for the adultery charge, think carefully about what it will get you. It may be worth it, I don't know.
We're in very different places... but I did want to share with you that once you've been through your own emotional divorce, I hope (like me) that you find the water on the other side is very blue, very calm and the sun shines... it really does. I'm happier than I've been in years. I wish all of that and more for you.
