Something I'd recommend you take a look at is Gary Smalley's personality profiling system. It's kind of a cool way to look at different personalities, and I believe it can help in how to think about reconciliation attempts.
It's quite possible that your W fits under the classification of the "beaver personality". Based on your posts, she demonstrates some of those types of behaviors such as depression and negativity. Check it out and see what you think. You can find some different information on how to best deal with each type of personality. Just google smalley personality type and you'll find all kinds of info.
