Ever since primary dd (13) has been losing friends. She builds up friendships, for a while all seems fine, then they move on, and her heart, and mine, gets broken 
She and I just can't understand what the reason is. All I can think of is that she has quite a serious nature and isn't into anything in particular, so I worry the friends find her boring? Even though she's not at all, but maybe to a teenager she is? Not that I'd say that to her. What can I do to help?
