i need an many_many relation between all Pages that is maintained on both ends

for now my code looks like this:

class Page extends SiteTree {

static $many_many = array(
'Pages' => 'Page'

$pagesList = DataObject::get('Page');
$fields->addFieldToTab('Root.Content.Relations', new CheckboxSetField('Pages', '', $pagesList));


but i want also the Checkboxes 'checked' that are related.

So I need a way to ask about the PageID that is related to the ChildID to get both ends of the Relation. Also for the Controller-Class
