The implication of giving the ribbon is "something to remember me by", and I'd wager the setup here is one I've seen elsewhere, where the highborn young heiress is set to be omiai-ed out once she graduates.
Even without that fillip, she doesn't want keepsakes, she wants Dia — and if she can't have the latter, there's no sense in having the former. Kinda better to make it a clean break.
