You and Joe were bestfriends since childhood. You were the only one knowing about his obsession issues and stayed as his friend and he was grateful to have you

You knew that he was dating someone but also knew that this someone cheated on him and he found out and you knew that he was gonna go crazy and start doing his crazy stuff so when he visited you pissed of after finding out about his girlfriend cheating on him, you have decided not to let him go crazy again

"I cant believe she cheated on me"He said completely going mad, his voice rising as his anger got out of control
