Making your crush feel happy when with you should be your first priority if you wish to take the relationship forward. The reason why this is so important is because when you make her feel happy, it instantly makes her feel warm about you. Your girl will automatically become friendlier with you and open up about at least a few of her inner secrets. Gently nudge her into talking about things that make her happy. It could be anything right from exotic vacations to everyday eats. This way you can quickly get into her good books and ask for her phone number.
