I started to going out with my classmate, but my best friend told me , do not do that, becus, he os younger than you, Then after that I tried to do not go out with him, but still I love him, now adays I realize that my best friend is interested on him, they are flirting each other and texing each other, at first I could not believe it, but it is true. I feel really dump becus I think he move on her, what should I do. I really love that guy.
