Your WAW is a stubborn one.

That being said remember!

"don't believe anything they say, and 50 percent of what they do"

It's true your W could have turned into this cold calculating alien. Most likely she is still the same emotional (and as you said before, depressed) person you know. My theory is that she is trying to remain strong and hide her emotions. Who's to say she doesnt cry all over the keyboard when typing, or she avoids seeing you to show a strong front. Keep being strong yourself she needs a rock to lean on, show her it can be you.
