I agree with ACJ -- it sounds like your XW really appreciated the gift (and not so much the gift as the the THOUGHT that is obviously attached to the gift). It also seems to me that your XW still has some confused feelings going on, and may be reaching out to you in subtle ways in order to possibly tell where you're at emotionally. The examples for this are her saying she doesn't deserve your kindness, or her says that you are happier without her since she is a real B, etc -- she's maybe trying to see what kind of response you're going to give and see whether or not it will tell her how you feel about her
IMO, you should continue to commit RAKs (Randoms Acts of Kindness) with regard to your XW, but do so in moderation. Obviously monitor the results and adjust accordingly. Just focus on doing what works, and it seems to me that doing the occasional RAK is currently following this path.
