Color me confussed too then!
Wow!
My kids were just lucky. They were seperated for many years before finally being put back together with us (there are 3). If it hadn't been for the cwr J had and his sibs coming back into care, they probably wouldn't be together today. And J's last fp's were very pushy about getting them together. They have worked in the system, so they knew who to push.
Is there anyone you can rattle their chains, so to speak, to let them know in loud terms that you do not want to adopt, that these 2 NEED to be together? Do they visit? They can be the biggest help in this matter. The more they beg their cwr's and therapist and everyone, the better someone might listen.
Wish I could wave a magic wand for them. <sigh> Hang in there.
