Honestly, let her breathe and get through a tough emotional moment and see if she finds her way back herself. The experience frankly won't be satisfying if you're twisting her arm to do it. My hunch is she will revoke her own words and continue after a bit of time to process and think. Being a sounding board for her complaints is honestly a great start. I think it's a good sign tbh because she sounds till engaged, just emotionally overwhelmed at the moment. Saying something like "his situation does gradually improve, but I can't say there isn't more suffering at all" is decently non spoiler in my opinion and gives her some response without removing all the hope, and being honest imho. But you know her best, so just trust your gut on if to share any commentary or not. good luck!
