Need Advice

I'm not sure what to do now. Hubby called me and said he had a lengthy conversation with the SW's supervisor in Idaho where our Niece is currently. We have done everything they asked and became licensed in November in order to bring her here to live with us. We were promised a decision on her permanent placement in November, then in January but that isn't happening right now. We were finally told that whatever we were told prior was not completely correct and that it could be a year to 5 years before we could bring her home (if they even decide our home is the best one for her). She is currently in a foster care home and they also wish to adopt her. They even told the SW's supervisor that they ara afraid they will eventually get the call to pack up her stuff to ship her here to us. While I feel for them they need to understand we really hope that whatever is decided is the best for our Niece. We are pretty upset about the entire system and really want answers but find now it aint going to happen to it happens...once the TPR is approved then hopefully we'll know something more. But until then we have no information as to what is going on with the hearings or anything else involved in the case. We get bits and pieces from here and there and then it all changes . We have our license and we can't use it. We were told today if we take in kids during the waiting period that will hurt our case to get our Niece. Their reasoning was they want her to be the ONLY child in a family. Well, we already have a 12 yr old daughter so I'm not sure what that means? And who's to say the foster family won't have more kids? I don't understand that statement at all. I really want to foster to adopt a child, be it our Niece or another child here in our county, but we are stuck as to what our next step should be. Do we just tell them in Idaho we wish to stop pursuing our Nieces case and allow the foster family to adopt her? Or do we stick it out and not know when this will all come together? I really don't wish to give up on our Niece but if she has a great life now then why make her stay there and down the line end up having to come here? But then again I want to keep her in the family and we really love her and want to adopt her. My husband also spoke to the CASA person involved and she seemed to be quite partial towards the foster family adopting our Niece...so much my husband came home and said he thinks we may not get her. She seemed to not be interested in our situation at all. Is this normal for them to be that partial? I guess I just needed an ear and advice if anyone has any. We only want what is best for our Niece. In the meantime my husband has asked DCF in Idaho to forward our phone number to the foster family so we can speak with them. Maybe together we can decide what is best for her.
