I don't think anyone has been as dramatic as people are saying and it is never being a "twit" to consider the child's feelings over the adults in any situation. This is a girl being shuffled around like a prisoner and now she is randomly at her Uncle's with random fuck buddies spending the night and coming and going as they please. It is not an ideal situation especially how it was portrayed in the first few posts. It is never wrong to consider how a troubled kid may feel about a situation especially since her sense of trust and stability has probably been shot to hell-I think that is the responsibility of any adult in a similar situation.
Hearing more about the specific situation makes me think what the OP is doing now isn't damaging, but perhaps even helpful because it seems like every other adult in this girl's life has no idea what to do with her.
