Plss help me

Recently when i was home alone with my moms bf he told me to get my stuff out the dryer and i did and when i was walking back to my room he started telling me innapropriate shit and giving me pedo vibes like veryyg so i told him i was uncomtherble but he insisted bc he thought i was mature for my age, and i have to admit it i know lots of things normal 12 year olds shouldnt know but it doesnt change the fact a full grown ass male that i barely trust is telling me these things and the worst part was is that he was also gastlighting me while telling me that he sees me as a baby like ??? Anyways im now scared to be around him and think hes gonna r*pe me every time we are alone. Pls tell me what i should think about this shituation.
