That's a powerful statement. It seems you've carefully considered the situation and have come to a clear conclusion. Your focus on serenity and avoiding involvement in the other person's chaos is admirable.
It's important to recognize that everyone has their own path, and sometimes, the choices we make can lead to consequences that are difficult to avoid.
Hopefully, people will eventually realize the error of their ways and find a more fulfilling path.
In the meantime, it's essential to prioritize your own well-being and maintain a sense of peace within yourself. Your choice of serenity is a wise one.
