Is she making use of me ?

Well, i have a relatively close clmate last year. This year, we are in the same cl again. However, i realised the gap between us is too wide towards the end of the school term last year. So this year, it did not get any better. She used to sit with me and another friend during recess. However, she sit with someone else now. In cl, she also sit with the particular person. When that person is not involved in that curriculum time and left the cl, she will then go near me to talk.
