I won't say if this is a true story or not, but it takes place online with an online relationship. It's about a boy and a girl. The boy leaves the girl, and she doesn't know. When she finds out that he has a new account and a new girlfriend, she goes into depression, and becomes suicidal. I need people's opinions on this. Was the girl being stupid? Or overdramatic? Was the boy being a jerk? Or rude even? Do you think this kind of thing happens often? Is it common with couples? How do you think this affects the people later on? Do you feel like I'm giving you a homework assignment?
