Could i have done something differently to make her want me? iin

About 5 months ago, finally after 6 yrs I told someone how I had feelings for her ever since that "moment" on the beach. I am a 21f and id never felt this way before. I told her and she said she already knew & that it was OK. The conversation went on for a bit and I asked "I thought we had a connection"? As she said a while back, that we had a connection & it was intense, kind of like romance. She told me we do have a connection & she does love me but its different. Its not sexual. She said she can't give me what I want which is a relationship. She can't give me her full attention. She said it doesn't matter if we are the same sex & she would have pursued something otherwise. She also said "What do u want to do about it? idk how strong your feelings are". I don't know why she asked me that as obviously nothing could be done! I really dressed up that day, was going to take her to the waterfall and tell her, to try make it romantic. Maybe I should have told her sooner ? Maybe I left it to long ? I swear she used to flirt with me! She could be in denial! I still wonder if she did feel something but is afraid to admit it?
