My stepsister moved in with us about two months ago.. She would keep tryin to get with me.. she would sleep in my bed and call me all the time.. we fooled around a few times and she even kissed me once.. then all the sudden she says this is wrong your my brother and would still continue flirting with me and sleepin in my bed.. when i try to talk to her about why she would flirt with me and sleep in my bed she would say i dont know what you are talkin about, which i dont understand cause i know she knows what im talkin about.. she would purposely try to make me jealous by callin all her little boyfriends whenever she is around me and i wouldnt care and told her to go away.. the other day i asked her if she was just fakin everything that happened a couple of weeks ago, or if she is just fakin like she dont like me and dont know what im talkin about.. please help me i like her alot and im confused about her mixed signals she is sending me
