Oz, I only have a moment to write but I’ve read and thought about it. I strongly agree with AnotherStander’s logic. The 49rs threw long passes (fail) at the end of the Super Bowl because time was running out.
Since it’s a bit of a negotiation I’d take time to consider what you really need from her vs. what you can get from family and cancer support groups. I remember her pulling back when you talked to her about the reality of your cancer. Maybe it’s the dates and fun feelies and possibility of romance and sex you crave?
I don’t think “terminal cancer” is a dating dealbreaker. Frankly, for a short-term relationship people are more focused on your charm and physique. How many initial bar conversations even turn towards health status beyond STIs? For that matter, items that’s be dealbreakers for me and many others (e.g., smoking) may not be for you because your partner getting lung cancer in 10-20yrs is probably not chief among your concerns. That’s only one example.
