I just saw this situation in my newsfeed. This seems like a gray area, especially given you don't have kids - not really a right or wrong answer. Maybe a "Saw the hostage situation oh the news - are you OK?" Something about "please just tell me" sounds a bit antagonistic, like he won't respond to any other inquiries.
Me:30 H:29, no kids T:12, M:4 (when D was final) 12/13: "Don't think I want to be M anymore" 6/14: Separated (I move) 1/15: H filed for D 5/15: D final
