Family drama? Can't lave my niece?

Unless your brother is in jail, call him and tell him to pick up his child, That 3 year old is way too violent and destructive, probably has issues already without a mom. But , that is your brothers problem and not yours, Your fiance is not responsible for talking care of your niece either, I can understand why she left. You stepped up to the plate, but you lost the game. Call your brother now.
