If they ask for advice don't bother giving it. Just tell them that it sounds like their situation sucks. From what I've gathered in your comments it sounds like they want validation not advice. Or just cut them off completely if you hold no connection or love for them. You don't have to keep toxic people in your life. But I don't know your situation, and maybe your question was more rhetorical.

If that's the case, I'm sorry that sucks. Not much you can do 🫂
