ME and girl love each other but she doesn't ever want to hangout?

We talked everyday every single period in school last year. We somehow had 7/8 classes together.everything was so natural when we talked. She said she liked me the entire year. When school ended we texted every day in the summer 24.7 from goodmorning to goodnight. I missed her desperately but she never would want to hangout. Finally the last week of the summer one day she decided to hangout and it was amazing! We talked, laughed so much, and then she brought me next to a river and we play fought in the river and then i picked her up and laid her down and we started making out. We were like a couple for that one day we held hands kissed etc. That day was august 31st. Ever since we haven't hungout once! We don't see each other in school at all. We still text alot and we admitted to loving each other. Everytime she makes plans to hangout she cancels or something. She told me around september 20th because i got mad at her, that the reason she never wants to hangout is because she gets extremely nervous around me. I'm not going to lie either, i get butterflies around her and i never have gotten them before. WHAT DO I DO? We text everyday and its so natural even in text. We both have iphones so it makes it so easy to text fast we don't even exit out of the messages. We have a 4 day break starting today and we go back to school on monday. Please please help! Thank you.

Added (1). @sydney that is the dumbest thing i've ever heard… We're 15 i have never bought her anything in my life lmfao?

This doesn't make any type of sense. You guys text all the time but don't see each other outside of school? Are you buying her gifts or giving her money? It sounds like you are and she's just using you and keeping the seeing each other to a minimal.
