择天记有声小说全集:My bestfriend got a new bestfriend

hey..i became friends with this girl who was in my class when i was 14(im sixteen now) and soon we became the closest of friends..then the next year we had to change classes and she made a new friend in her new class..i kinda stick to my old circle of friends which includes her.i felt very sad and insecure as she became much closer to her new friend..all the things that we used to do together are now what they are doing.although we are still close..i dont think im her best friend anymore..and i dont blame the other girl as she is kinda nice.this has got nothing to do with jealousy as i cant stop her from being friends with ppl..itz just that i feel disturbed alot whenever she comes to me and tells me stories of how she and her friend hung out at this place and so on..then again.i dont want her to noe what im feeling as it would seem as if im very selfish..what should i do?
