I've been dating my girlfriend for almost 3 years now, we shared our first kisses, we took each other's virginity, we've been together through the deaths of loved ones for each of us (my mom, her uncle). But most of all, we are genuinely in love. I enjoy every minute we have together. I also plan to marry her when I get out of school and get a job that pays enough for a wedding. If we found out she had cancer or something and had a few months to live, I'd try my dammedest to make them the best months of her life. Though, I'd try to prepare myself emotionally for when she does kick the bucket and try to get back out there.
But, I suppose if it were someone I wasn't as emotionally invested in, someone I'd only had a couple of dates with, I'd probably be like, "Sorry, gtg."
