My girlfriend doesn't appreciate me. What do I do?

Ok so I had been dating my girlfriend for 6 years, and we’ve been for the most part very happy together. However, last night we were fighting about something. More than a year ago, my girlfriend told me that if I don’t show that I want to live my life with her (aka propose to her), she would break up with me. So about a couple weeks later I proposed, but I completely screwed it up. So then 10 months later, after thinking hard of what I wanted to do to propose to her again, I ended up writing in the sand on the beach of how I felt about her, and asked her to marry me. THIS time I felt it, straight from my heart. She seemed to love it. But just last night she admits that she didn’t feel that I proposed to her correctly…. again. I was so heart broken when she told me this. She had been showing me “cute” proposal videos of guys singing to their girlfriends, and saying that she was jealous of that. She said that I should have “given it my all”. But I did. I did it with full confidence, (which men RARELY ever have), and said it with all my heart. She was expecting me to do something like make her a video or include photos. She said she didn’t feel a thing. I know she loves me, and she does a lot for me, and I know I do a lot for her. But getting married isn’t about a PERFECT proposal or the PERFECT wedding. It’s about living our lives each and every single day, thanking God that you are living with such a great person. I know that she’s the one for me. But I think her views on marriage are very warped. What do you guys think?
