Should I separate dying Guinea pig from cage mate?

I’m incredibly sad that poor Eleanor has piggie cancer. She is in pretty bad condition - wobbling around and easily looses balance. The vet gave me some liquid food and meds but she is also still eating vegetables/pellets although not really hay. I’m not sure if I should separate her from her cage mate? The vet said I probably should but it’s so sad to see them apart! I was keeping them in the same cage but with a barrier but I wonder if they want to be together. Eleanor is the dominant one so I’m not sure what the dynamic is.
