Saw this at a website I chanced upon. It mentions things a boyfriend or girlfriend should do... not sure if this is too ideal of a scenario...
[1] Call the next day
[2] Always laugh at his jokes
[3] Tell him (truthfully) that you can't wait to see him again
[4] Offer a backrub, without asking for one in return
[5] Call him just to say you were thinking about her
[6] Bring him a teddy bear and chicken soup when he is sick
[7] Write him a poem
[8] Slow dance with him(not only on a dance floor)
[9] Bring him flowers for no reason
[10] Send him a (handwritten) letter just to say hello
[11] Always remember your anniversaries and bring him something sweet
[12] Kiss him in the middle of a sentence
[13] Take him for a walk at sunset and stay to look up at the stars
[14] Tell him something about you that no one else knows
[15] Remind him that you still think he is cute
[16] Take a bubble bath together
[17] Watch a sappy movie with him
[18] Surprise him with a candlelight dinner
[19] Never stop trying to impress him
[20] Tell him you love him and mean it
[21] Never forget how much he means to you
[22] Give him great big hugs for no reason.

I know... I edited the thing just so that it applies to me... hehehehehe... I'm not giving hints... just thought that this list was cute. :)
