Should I stay or go?

I 38M have been struggling if I should attempt to heal and mend a relationship with 39F. We have been through a lot. She’s in a tough spot as I am. I am going through my healing journey, and I want to do it with her, but she’s basically given up on life. I feel I need to be there for her, but I also am not sure I should leave. We live together but I can tell her it’s time for her to move on. Should I try and mend this because I do love her or take the loss and tell her we’re done?
