My experience with abusers is that they always do things for themselves. They think they are good people, so sending a gift would, in his/her mind, be a way to further convince themselves of their goodness or rightness. Also, with some underlying motive to tell you you're wrong about them. At least, that's been my experience. Even in the face of a confession, they make themselves the martyr or victim. Once you get free of it, it's kind of fascinating to watch.

And yes, wrap that sucker up and take it to your therapist. Too bad safety codes do not allow a bonfire, because that might feel very satisfying.
