I don't Want to Move!?

Well, it sounds like there's no changing your mom and boyfriend's opinions, so try and look to look on the bright side! I moved when I was 6, so there never really is an age when you're 'too young to move'.... and you never know, you might make new friends and stuff and end up liking it. If you really hate it that much, talk to your brothers and come up with a way to try and convince them.
