Thanks, Hawkeye and ReadReadRead. Yes, I was scared last night. But his message, when I finally listened to it, was rational--just that he wants to talk to me. And he didn't show up at the door, thank goodness.
Today he's continuing to call, and I'm not picking up. Tomorrow morning I meet with my (new) attorney, who has experience in these situations. The RA attorney that I thought I was going to retain acknowledged that she's not a fighter, but she was able to refer me to someone who will go to bat for me and my children.
My AH isn't usually violent unless he's been drinking. My guess is that right now he's decided to get sober (again), so other than the nuisance of needing to fend off further circular discussions, I should be okay.
