You moved out back in August and returned home. A week or so of making nice and the blah blah is not recovery. Nothing changes if nothing changes.
Meth is a very dangerous drug and is often associated with rage and violence. Law enforcement has special protocols for dealing with Meth addicts because behaviors are so unpredictable. If the law takes special precautions, imagine how exposed you and your daughter are. At what point does rage turn into physical violence?
I cannot imagine knowingly exposing a child to anyone with an addiction to Meth. Your primary job is to protect her. People loose custody of their children for failing to protect them.
Is your daughter's bio dad in the picture?
