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

[Wired Jokers]

As I have aged, I have realized one of the most important truisms in life is this:

"In life, you almost always regret the things that you had the opportuntity to do, but found an excuse to avoid or ignore. Rarely do you regret the things you did do, no matter how difficult or wrong they ended up being."

A lot of the younger posters on these boards will have no idea what I mean. But you will.

From your description of your relationship, if you do not visit this poor man, you will literally regret it to your dying day. Please go see him.

Your relationship with your ex, to me, is completely irrelevant.
