How did you feel when you said goodbye, and got a brush off goodbye?

If it set you back in terms of detachment.....then stop doing it. If you can hello and goodbye to her with no expectations, and without being hurt or upset when she doesn't reciprocate, then by all means keep extending that "common courtesy" to her.

Personally, I've never been a fan of pushing myself on anyone that doesn't want anything to do with me, no matter who it is. There are people in my life I completely ignore because when I say hi, or have a nice day on departing from them, they act like I am burdening them. So to those people I do not waste the time or energy to extend common courtesy.

As far as what the behavior means.....it doesn't mean anything. And it is a fool's game to try to get into the mind of the WAS. Likely she doesn't even know what it means, how could you or we?
