Show her affection. Girls want guys to show them affection because it tells her that you care about her, and that you're willing to show that love in a public way.
Tell her you love her. Make sure you mean it. If you're not ready to go there yet, that's fine. But, be sure to switch that
"I love you" for a really good "You know how special you are to me?" or a "I like you so much; I'm a really lucky guy."
Put her first, yourself second. Put her needs in front of yours.
This does not mean that you are weak. It just means that, most of the time, you're willing to bend for her, even if it was not something you wanted to do.
