I'm asking this for a friend since she's currently in this situation and she wants to tell her mom about it despite that her mom is extremely sensitive and emotional. My friend says she wants them to divorce because it's unhealthy to stay together and because they can't handle things themselves. She said her mom is staying in the same house for my friend and her little sister's sake. I want her to stay out of it because it's none of her business and so she won't end up being homeless. What would be a better idea?
