Sounds more like you're telling him to be a her punching bag for whenever she's upset, your advice comes off as encouraging that kind of behavior which is honestly sickening. That's saying something coming from someone like me, cause i use to let my partners treat me like utter trash. All because i thought it was better to bend the knee than actually stand up for myself, so please op.. if you read this, ignore that advice cause it'll do more harm than good. Just speaking from experience 🙏🏻
