Being unsupportive brings bad feelings into the family. My kids are adults, and I don't always like what they do, but I try to support them all the way. You are an adult, and have the right to make decisions on your own. Try to talk with her, and explain why you are moving. If she still doesn't come around, it is not your fault. She will have to come to terms on it on her own. Best of luck with your new move! Moving can be so stressful for all. Don't let her ruin it for you.
