Islam didn't make it haram for you to fall in love. It didn't forbid you from wanting someone. It only guides that love so it protects you, her, your families and especially saves you from humiliation on judgement day. If you love her so much, why are you okay with letting her engage to this unquestionable relationship knowing full well that she will have to answer just like you will. You don't love her enough to save her from that?
