On the flip side (pun intended, get it? I guess CDs don't have a flip side like records did, but anyway...), your w asked for a small gift (just a CD) and you didn't get it for her! She may be seeing your actions as you not thinking she's worth the effort to get out to a store and pick up a $12 CD for her. And you didn't get her anything else either, except a card. All at a time when she's feeling sad about her dad and you're supposedly working on the m. From what I read, you have a w who needs A LOT of assurance. She told you what was important to her (and you didn't agree that it was important) and you ignored her and expected her to be happy anyway. I agree with the others that she acted very childish about it, though, and I don't see a problem with you letting her know that.
