Thank-you for your post regarding child custody. It is a very challenging topic especially when manipulation and abuse are involved. The topic of parental alination however, is a trigger for many people as the original science behind the concept was found to be flawed and bias against women, partictulaly those contending with Domestic Violence. While Parental ALinaltion is recognized in some form by courts it has not made it into the diagsnostic and statistical manual for lack of good research ( the last time I checked . may have changed with DSM). In any event emotional abuse is often overlooked in court setting, sadly so is family history of domestic violence when it comes to parenting plans in many states.
Again thanks for writing on this very important topic.
