How can I get a girl to see how amazing she is?

I met this girl on new years and we were seeing each other a lot, going on dates and sleeping over. She would always tell me how much she liked me and how close she was to calling it love, then one day she started pushing me away, but didn't completely remove me from her life, she'd occasionally message me, and I always felt like there was still something there. We spoke in person the other day after not seeing her for a few months, and she still had a keychain on that I'd bought her for Valentine's and remembered small details about my life that she asked about. Then she told me she pushed me away because she felt like she was a burden and didn't want to bring me down by being with me, even though she made me happier than I'd been in a long time. What can I say or do to help her see that she's perfect in my eyes and how much I want to be with her?
