As for Lina, she said, "I feel like I can be more myself than I have ever been and enjoying every minute of that at home or at work. I am embracing life to the fullest."
Since writing her story, Diane has received more than 300 e-mails, many from readers who say they have never written before.
One praised her for helping her better understand in "a more real and compassionate way."
"I am an educated person and quite liberal, but while superficially being accepting, have found the transsexual issue rather difficult to absorb," she wrote. "I am sure it took a lot of courage, and I applaud you and want you to know that you most certainly contributed to the world in a very positive way."
Diane said she feels a "deep gratitude" for how they have sustained their marriage, but would never suggest their decision be right for everyone.
"You have to be open-minded and not fixate on what other people think," said Diane. "And have a strong sense of self, and some degree of flexibility."
"Look at the person who is transitioning as a human being and try to understand their side of it and don't look at them as a monster," she advised others in a similar situation. "If I had love in the beginning, I still have it."
