They are the best thing in the world but lately, my one and only friend, my best friend whom I have known for 11 years doesn't want to hang around me anymore. I guess it's cause I'm boring or dull or something anyways I go through moods about it for example one moment I think he's just busy and needs a break and another I think I don't need him anymore I can move on. What should I do? Its really starting to trouble me.
