did I save him?

i have two close friends a girl and a guy who were in a relationship about a month ago the girl confided in me that she had been with someone else behind his back what really got to me wasnt just the act itself but the way she told me completely casual without guilt like it was nothing

i sat on it for a few days of knowing something he didnt so i went to him and told him everything he was hurt but he thanked me for being honest we talked it through and both agreed we didnt want someone like that in our lives so we cut her off together

i dont feel bad about it she made her choice and i made mine i refused to be part of her lie

just wanted to get this off my chest
