A while back I was walking and bumped into a girl by accident. She started screaming at me, and asked me if I was blind.
Her boyfriend was next to her, and he told her to calm down.
She was really angry that he defended me, and she walked off.
He stayed with me, and apologized for her behavior. He told me that dating her was really hard and that he wanted to end it. He also said he didn't know how to because she was mentally ill, and breaking up with her would kill her.
A few months after that incident, by chance I bumped into him again. He told me he had broken up with his girlfriend a while back because he found out she was just pretending to be ill.
