Take it slow, no need to take things fast. Fall in love slowly over time, instead of rushing straight into it. Make sure that she’s the one, be able to read her like a book, know what makes her happy, know what makes her sad. Don’t piss her off on purpose, or go out of your way to get her jealous. Don’t be the guy that deliberately lies to her face. Be the guy she can fall asleep on, can talk about her problems with. Be her best friend, treat her like a princess.
