Leave a love note.
I remember a friend of mine telling me how her and her husband left love notes for each other every now and then. I thought this was a lovely idea. Several years later when I met my husband, I was thrilled when he left notes for me. find one under my pillow, usually on days when he was working away, or would go out to my car and find one under the windscreen. Amazing how the simplest of gestures can mean so much.
