Send her an invitation with an RSVP. Take her to a elegant, romantic restaurant. One that she has been wanting to go to for sometime. Do not tell her though where you are taking her, let that be a surprise. When you are nearing the restaurant watch the delight on her face. And to add to this excitement, buy her a bottle of her favorite perfume, have it rapped and while she is in the shower place the rapped package on the bed. What a joy you'll have seeing her receive that gift!
