I have a problem here. I have tickets for the upcoming 5SOS concert and I'm going with my friends. The problem is that one of the friends I originally going with has ditched us for other friends. When my friend, Glenn, and I confronted her about it, she claimed to still be our best friend. It is clear that she isn't. Glenna and I feel that she is using us for our tickets to the show. What should we do? How should I handle this?
