Advice on moving towards more open adoption

Just a quick update. I had set up a FB page and sent them a request but hadn't heard back. Just before Christmas they accepted the friend request, but no other contact. I set up the internet phone number and forwarded it to my cell so it doesn't cost anything but they can call if they want. And I sent it to them via fb message when they accepted the friend request.I'm hoping that this means they have a phone again, but I'm not sure. So, in the meantime, I'm just going to keep updating FB and sending the agreed upon updates and wait to see if they initiate contact again.
