For one, be yourself. Never act like your cool or like someone else. If shes dating you because of your personallity, then you should keep that.
Don't brag that your dating, a relationship is something special, not a bragging right.
Take it slow, don't ask her out and grab her butt or you're a goner.
And don't ask the forum for dating advice, you'll get a ton of trolls.
Hope the best!
