I so get this. I feel the same way. Once I asked T if we could practice her saying 'no' to me. My idea was that I would begin by asking for ridiculous things like, "let's run away with the circus' or 'would you come to my house and cook for me everyday?" And then possibly I could learn to ask from her 'real' stuff and wouldn't be so devastated if she said no. But T wouldn't play that game with me. She wants me to instead grow within myself, yadda yadda yadda.
