Great story.
I'd say the groom is a hero too. I worked with a woman whose husband left her when she was diagnosed with inoperable cancer. A family friend started looking after her. A month before she passed, he proposed and they were married a week before she passed. Believe it or not, some really ignorant people said this family friend was a fool for marrying her -- after all, she was going to die. But he stayed with her and cared for her till the end.
Men like the groom in this story and my co-worker's family friend are heroes in my book.
