Is one of her new friends a boy ?
There you go, she must like him then
Everything is a cycle, you've got to let it come to you. And when it does, you will know what to do ...
maybe invite her to go to the mall or something. although you have to understand that she wants other friends, and that she will want to hang out with them. why not go with her to meet these friends? who knows, maybe you all might be friends.
