I’m not using this term lightly but without being officially diagnosed and after years and years of him causing family upset through lies/manipulation and addiction my brother is a narcissist and genuinely worries me about how destructive he can get, my partner does not want him to be around us and our child which I completely get and I don’t want to be either. However, my question is has anybody detached from a narcissist successfully completely and how did it go? I’m scared that if I do it will cause a huge reaction from him and the anxiety of it all is a lot. I need to disengage as I have tried with him numerous times but it’s not healthy for me and my family to be around his behaviour anymore.
