Ex-GF's father diagnosed with cancer. Suggestions?

[inishowen]

Spoke to her for first time in 2 months this morning, she told me about her dad. He has "oat cell" carcinoma from smoking that has spread, prognosis is poor, mortality is 95% certain. They find out Tuesday if the doctors want to initiate a treatment plan to extend life or do nothing and prepare him for hospice. I got along great with her dad and still have strong feelings for her. She's an only child, parents are divorced. She is commuting 150 miles roundtrip daily to be with him. We are not together, but I want to help any way I can without imposing the topic of "us" on the situation. Any suggestions?
