You can’t control that, but hopefully she will. Is she making healthy decisions? You can guide her that way & try to get her thinking about what to change (if anything). One of the most important ideas is not to give to people or causes that don’t give back. Is there a hobby that inspires her? Perhaps you could do it together. Ultimately, sadly, if she’s not making it, don’t overinvest yourself. You have happiness to live out too.
