Glad to hear from you! And glad your ex finally got nailed--he is one scary dude.
Have you let the prosecutor know he's subpoenaed the girls? You can contact the victim/witness advocate, who might be able to help with counseling for them, could probably be in the courtroom with them, etc. Either way, they should be getting some counseling, and you might want to talk to the school counselor.
Hugs,
