...but can't understand that I don't want to talk to you or hear from you EVER again

Right... so that's why she sent you this text. She doesn't want to hear from you EVER again!!!

Seems like we've heard this before. I wouldn't reply becuase there really isn't anything you can say. She is obviously trying to bait you into a discussion.

Wait a couple of days, then send her another "I'm doing fine" e-mail...
