You're not getting the straight story from someone. In fact, the message, whether spoken or unspoken, seems downright caustic. A pal of yours doesn't include you in his or her plans. Sure, they'll call you when they need money, a ride or a shoulder to cry on, otherwise? Not a chance. They're using you. It's time to broach the subject with your so-called friend. If they get defensive, you have your answer: this friendship is over.
