I’ve not read the book and don’t generally follow Mel Robbins. But I’d say it’s how I’ve always operated. 😂 I don’t think it means to never let anyone’s behaviour bother you or to have any feelings about it. Of course, that’s a normal healthy human reaction. It would be really unhealthy and unnatural not to have feelings in reaction to other people’s behaviour.
But you can’t be controlled by your response to their behaviour and you can’t drive yourself into the ground mentally and physically trying to make someone act and feel the way you want to.
I have a family member who is quite unstable and manipulative. All live laugh love to the outside world, but behind closed doors, very much living a lie, deceitful, playing people off each other, to keep up appearances and a certain image and narrative. I wanted to help them get out of their unhealthy relationship and get some mental health support, but they just won’t take it. You can only try to throw someone a life raft so many times. If they truly don’t believe they need to change, then you let them. But you set boundaries that keep yourself healthy and well.
We are NC. I’ve let them live with the consequences of their behaviour. It does mean they are quite isolated. They’ll have no one (besides paid help) to care for them when they’re older. They have no family and few friends. My wellbeing is more important than theirs is - to me, anyway. So my focus is on me and that has positive effects for everyone around me, my husband, my kids, my friends, my extended family, my work, my pets, etc.
You can’t change other people. You can’t make them see how it feels to you. You can’t make someone have empathy or seek help. You can change how you let it impact your life. It’s about boundaries but also acceptance. You can’t have compassion for someone, but also say, nope, not on my watch you don’t!
