Oh geez, wasn't thinking when I wrote that. She's still alive afaik. I don't know if she would've followed through with it had I not called, but I'm happy I didn't have to find out.
Knowing her, I don't think she's ever going to speak with me again, although I hope time tempers her and she's willing to reconnect one day as others have predicted will happen.
I was pretty aware of what would result from my contacting police--that she would not be happy--but had to do it regardless.
