<human>: Give me a shortened version of the text

We've been friends for about 3 years, always been close, I've helped her in many relationships, we've had many heart-to-heart talks, and even exchanged drunk texts. She told me that she would feel uncomfortable in a relationship with me because "she knows I deserve better," but truthfully, all I want is her. She makes me happier than anyone, and she told me the same. I know I'm just 17, and I know she's unlikely "the one" but I really want to try a relationship with her.

I asked her on a date, she said yes, but when I asked her to be mine, she said she couldn't. She said she would hurt me, and that "I don't know what she's like in a relationship" when in reality, I've seen her through a couple, and I really think we would be good together. 

How can I convince her that a relationship would be a good thing for us?
<bot>: Girl thinks I'm "too good" for her, she's amazing and we're really good for each other. How can I convince her that we'd be good in a relationship?
