YOu are such a sweet sweet person...Tell your dad that you would love to move anywhere with him...that you want to bring him joy and that he deserves it...but also tell him why you don't want to move to that area...My goodness he should know...If you tell him...I am sure you can compromise and find a place that you both would love...Don't cut your dad short...Let him be the man and father he would want to be for you...give him that chance...
and just maybe he won't be as broken as you think...!!!
