I think what is happening to her is that she realized life 'on her own' isn't grand. In fact it sucks and she misses you on top of this. Her pride has kept her in defense mode this whole time, but I think that is melting away. She is letting you back in....inch by inch...
You are awesome, the epitomy of lovingly detached.
PS: D5's birthday party is tomorrow night. Its going to be 'fab', send your D's on over!!
