Is it normal i gotfriendzoned by a girl that likes me? or so i thought she did?

Well after talking to her for 5 months I got a really strong feeling for the whole time we talked that she liked me.. alot, she would stay up late just to talk, blush and be shit when i would talk to her at school, when she was drunk she said she liked me alot (but idk she was drunk) and just all that shit. then a few weeks ago I finally told her i liked her, then she said friendzoned me and she still gets jealous and stays up to talk sooo idk wtf LOL.
