Kiss her every chance you get

Hold her close when she's cold

When you are alone hold her close and kiss her

Kiss her on the tip of her nose (it will give her the hint that you want to kiss them)

While in the movies, put your arm around her and then she will automatically put her head on your shoulder, then lean in and tilt her chin and kiss her lightly

When she complains that her neck/ shoulders hurts massage it for her

When people diss her stand up for her

Look deep into her eyes and tell her you love her

Lay down under the stars and put her head on your chest Link your fingers together while you whisper to her as she rests her eyes and listens to you
