Tell her why she's perfect for you. Pick her up and pretend like your going to throw her in the pool; she'll scream and fight you, but secretly she'll love it. Protect her. When someone insults her, stand up for her. Whenever you’re somewhere together, sit/stay by her all the time. Look at her like she's the only girl you ever want to be with. When she least expects it, pull her in close and kiss her hard. Tell her she looks beautiful. Tell her how amazing she is. Tickle her, even if she says stop. Get her mad, and then kiss her. Let her fall asleep in your arms. Call her. Just to talk. Give her piggy-back rides. Kiss her forehead. Write her letters. She loves them. When she's sad, stay on the phone with her even if she's not saying anything. Be slow. Don't push anything. Let her take all the pictures of you she wants. Say “I love you” before you go to bed each night. If something’s bothering her, show her that you care and try to fix it. Make her feel loved. Pay special attention to her. Kiss her in the rain. If you love her, tell her. Often.* -Internet
