Lexie, they are friends or at least the girl seems to think so and the guy certainly has confirmed this by acting as a friend. Since he has established, by his past actions, that he is someone she can count on for ride, if he wants to cease getting those calls and keep her out of trouble, he needs to sit down and explain it to her. Ideally, he would give her some alternatives to calling him (find out what drunk ride services are available in her area) instead of letting her think he can be counted upon only to find out, when she is in a potentially dangerous situation, that he cannot. I have no problem with someone drawing boundaries. I do have a problem with someone quietly drawing a boundary and not letting the person it effects know.
