I found this on another site. It was posted there from somewhere else, but was not credited to the original author. I think it really says what quite a few of us felt when our marriages ended. I hope you find it valuable, too.
"A person trying to hold a love together rarely gets the credit for
the bravery they show while their confidence is waning. There is no way
to explain how difficult it is to be in love with someone who suddenly
does not love you back; who changed one day while you weren't looking
yet continued to act ‘in love” and lead you on for no other reason than
their own fear of being alone. There is nothing that can help when
someone breaks the faith with you in such a cruel way, just understand
that it was nothing you did or failed to do. Hard though it seems to
believe, life gets better and you will, eventually, find the strength
to be loved again."
