Married life is when you have someone whom you can call your own. Rose is bound to her husband as long as he is alive.
And that will be more threatening and risky..
Life is so unpredictable. We didn't notice those who can love us until our last breathe, but would you dare take the risk to fall for a couple of weeks, when there is just a little hope that --- that someone will survive? Anyways, you don't know about it either because you, yourself was busy waiting for your own time to come.. to go and to vanish.
