Oh--another update. I got a voicemail from husband, saying, "The police have come today--I just wanted to let you know I'm all right." I don't feel like ringing back.
Then on heels of that got voicemail from his brother in [another large city, down south], who said that he'd also got a call from husband, and husband said he wanted to go down and stay with brother.
So who knows whether husband will be able to negotiate the trains, but if he does get to brother's, it will be a relief, because 1. safe and alive, and 2. not charging every meal to our checking account.
Going for run now.
