Need help and quick

I started my first relationship. It's a typical highschool relationship. Except I never see him anymore. We have no classes and I never see him to walk with him. Weekends aren't any better. We can only communicate through Twitter cause his phones broken. There's also another kid who I've been around a lot.. Should I stay with my boy? There's prom this weekend and I don't want to go and make him waste Money if I don't want to consider us together anymore
