conflicted

Anyone who's reading I'd appreciate your opinions.

When I first suggested home school to Krysta, she was interested, even happy about the idea. Then she went to school and obviously told her friends, who said they were upset if she'd go. Then everything changed and now she has the worst attitude about it. I'm really bothered.
I want to do this because I feel its the best thing for my family.
What voice in this should she have? I don't want her to be upset but I can't have her making the choices about things I think are important, when she is 10 years old.
Obviously we would provide other avenues for her to socialise and she can still stay in contact with her friends at school (who really haven't proved to be friends out side of school. One girl has come over once the whole year and she had a birthday party).

I really feel like this would be great for Adria, and definitely for the boys. So really, should I keep one kid in school just because she wants to? For whatever reason I don't really know, other than the friends. Because everything seemed ok til that.
Should I barter with a ten year old? Right now she is throwing tantrums about it and being really rude to me.
I'm pretty disappointed in her and her behaviour enforces more why I want to do home school!
