So a girl i know now says she hates me because of something she thinks i did before in the past to wrong her, but then other times she'll compliment me, ask me how she looks in outfits, tells me about her friends, texts me good morning and good night, and all those other friendly things, but then she'll do a 180 and say "I still hate you and think you're a giant asshole and that you deserve to rot and die" out of nowhere, then go back to being nice. What possible reason could she have to play both fields like that if she says she does hate me?
