I sent my W an e-mail like that and it did help, but only because when I sent it she was ready to receive it. You're getting good advice here about how to handle it. Based on the fact that it's risky pursuing behavior, just be sure your W is in a place to receive it versus that being wishful thinking on your part. If you've already promised to send it too late, but if you are projecting that your W wants to receive it then you may want to write it and wait. It's a great think to do but as with so many things in life timing is critical.
As others have said, the tone of the letter should be what you realized, how your values have changed etc., but it needs to be introspective with no "how do you feel about that" or "I'm doing this for you". If she reads any of that between the lines it will hurt more than help. It needs to be for and about you such that anyone could read it and appreciate what it says -- i.e. the reader can't be key to the message.
