Down part of the rollercoaster of foster parenting

Yesterday we got a little disheartening news regarding the case of our oldest foster son. We have had him since he was 7 months old and he is now 22 months.
Last month we were told that they (the DSS) weren't going to pursue the distant relative (cousin) and her boyfriend as an adoptive home. The boyfriend didn't pass the CORI. The young woman had something come up on her CORI, but it was waived. Some things that come up, really aren't a 'big deal' per se, so I don't want to judge whatever it was that came up on her background.
But, with that news, we were very hopeful that this would mean that we had a big chance of adopting "E"

Then yesterday we were told that they (the case workers) are going to give her a chance to reapply as a single applicant. I tried to be understanding, but I am so damn frustrated at the system. This will only prolong things no matter what the outcome is. I also don't understand why they would do this in the first place??? Her boyfriend lives in the home. He will be around "E" if they aren't found suitable together to be a permanent home for "E" it's not like they are going to break up and he won't be around anymore. Why start all over? It doesn't change the situation?

"E" is a child who has been in foster care since he was 7 months old. He was with another family for 2 months before he came to us. We have raised him for the past 14 months. We have been through so much together. Here he has a mom and a dad who love him dearly, a big brother, a little brother and a dog that he adores. Yet in the eyes of the 'system', we are not considered his family. To him, we are his only family. To us he is our son.

I understand the biological connection, and we are very open to having visits with his relatives. I want him to grow up with biological family in his life, but there is just no one in his bio family that have proven that he could be safe enough in their home to live with. If that was the case, then he would have been placed with bio family long ago. Forget the fact that we would be devastated if he were to leave here, for any child to be in the system for so long, in a home that is not considered permanent, only to leave can have very sad, preventable long term consequences.

If he is to end up with his cousin, I want to develop a relationship with her now. He needs to get to know her and the people in her home before he goes. It's not fair to take a child out of the only home they know and send them to live with strangers. When we went into foster parenting, we knew that the goal of fostering is to reunite the child with biological family whenever possible, but somehow, this just doesn't seem like the right possible thing to do.
I'm sure next week, there will be a new twist in this case.
