Miley broke her silence about the breakup, confirming that it happened ... but making it clear she doesn't want it to become some big dramatic deal. The singer says ... "Right now, two halves can't make a whole and we're individually just working on ourselves to become the people that we wanna be." She adds that she and Cody might be seen hanging out together still because they've been friends for 10 years ... and she says that's not going to change.
