My brother tried to rape me

I was 6 he was 8 ( I don't remember exactly) I love him still! We were playing the tent my Dad set up down stairs in the basement we were laying on the mattress I it and he told me to take my clothes off and I did because we were always bffs it was like da weird I k re it was off but I ignored that because we seen each other naked before. I DID NOT KNOW WHAT SEX WAS! he said do you want to have sex and I didn't know what that was so I said no. I am so thankful I did not know what that was at the time because of I did I would have lost my virginity to my brother. But after that he tried to get on top of me but I pushed him off and got dressed then my mom suddenly came down stairs with out either of us noticing and we were dressed at the time and then my mom scared the shit out of us, I Instinaly threw up in my mouth because I felt terrified by my brother and I got out and threw up I played it off as I was scared but I was horrified about what happened nobody knows absolutely no one. I am okay with it. I don't want my fam to find out but I am okay with what happened now.
