1. Make her feel important and fun to be around.

2. Don't flirt with other girls in front of her or any other time.

3. Give her chocolate's and roses to make her feel like a queen.

4. Talk to her ,understand and care of what she has to say.

5. Don't treat her like she is just some girl.

Sorry if this is not true to all of you but if i wanted a girl to feel this way this is what i would do. So this is the best i got.
