Hi, AFG. Good intel. I personally would pay the small amount for the full reverse lookup report, but that's just me. Such an obscene, harrassing phone call, properly documented, might be good to have.
I think you should say to your husband "Some psycho left a rather obscene voice-mail message for me on my business line, which I really don't appreciate. I'm in the process of finding out who it is, but I thought you should be aware."
Sounds to me like the message was OW, and it was intended for either you or H (not sure which), but there's clearly trouble in Paradise.
Just keep doing what you're doing!

P.S. I think you might have covered this before, but why do you eat in your room with your door closed? Your heart and emotions are doing VERY well, so I don't think interaction with your H set you back in any way, and this just makes you look "hunkered down" and defensive, IMHO.
