I kinda pushed my best friend's girlfriend to dump him.
Why did you want her to dump him?
Because he reported me to the faculty.
I understand that you feel frustrated at your friend, but getting involved and ruining his relationship is not a good thing to do. You are hurting two people for a petty reason and are being extremely inconsiderate of how they feel about each other.
WTF what happened to not hurting people? He hurt me first so it is his fault.
I am sorry that when he turned you in he hurt you but hurting someone back is wrong. You shouldn't have interfered in his relationship, he might not forgive you.
