I have a best friend.We shared our stories with each other.I never cheated her,I love her just like my sister.However,I found she sometimes kept her emotions or ideas to herself.I am afraid that she will leave me alone.I have a lot of friends,but she is the real one.Now,she has a new friend.I find our frienship is fading even though she does not admit that.What should I do?I do not want to be active to keep touch with her again ,I am so tired.However,I do not want to lose her.I am in a dilemma.
