Wife just told me doesn't want to be married

[Accuray]

I will go a step farther than Adinva -- don't give it to her, she doesn't want it. All it's going to do is make her feel worse and more responsible for your feelings, and she will resent you for that.

The scene in your mind where she reads your letter, suddenly has an epiphany and starts crying and apologizing is all Hollywood -- that won't happen.

Do write the letter, but write it for YOU, not her. Don't give it to her. One of the books I've read stresses the importance of not repeating yourself over and over because you're not getting the response or reaction you want. If you've told them once, and they aren't deaf, then they heard you and they know.
