AJ - none of this is normal. But in looking at your particular situation and comparing it with others, no, I wouldn't not say 3 weeks of cold communication from a WAW is abnormal. Think about it this way...she's been hurting in your relationship some for several years - now you're upset for 3 weeks. So, no, she isn't going to feel ready to warn up to you at this point.
As for detaching - remember that no contact and stopping pursuit is not the same as detaching. Detachment comes from an emotional separation of your feelings from hers. It's a goal...heck, it's practically THE goal. And it will take time. A LOT of time. Read read read the welcome threads on it.
