Erin, I am sorry you are going through this but it at least explains the distance your sister started putting between you {since she knew she was going to move} Maybe she thinks if you are mad at her then it makes her moving away easier on her and you? As for your niece, I am sure your sister in time will allow her to visit you for summer break. But having lived in upstate NY myself, don't be surprised if she doesn't move back home soon LOL. Just keep communication open with her and in time things will work out. Big hugs
