Leave him....?

When some women on here vent or tell a story about their SO I see so many people often comment “leave him”..... like ok thanks stranger? This is someone’s entire life we are talking about a real person and complex situations... are these advice givers gonna be their to support them emotionally or financially? Shouldn’t people be more responsible about the advice they give other people? 🤷🏻‍♀️ specially when they are venting and not asking for advice.
