Let him know you want to take care of him,
Laugh at his jokes (when they're funny).
Sometimes friends give the best advice on how to be a Good Girlfriend.
Let him know when you're excited, and let him share in that excitement.
Let him know you always want him to look (and smell) his best.
Teach him things.
Be caring and compliment him.
Give him choices (but not too many). Also take plenty of pictures of him so he knows you care (and can blackmail him).
For those of you who are curious, yes there are kittens in the photo.
No kittens were harmed in the making of this manual.
