Sexual Assault

when i was about 13 this girl, two years younger than me, tried to finger me. i told her to stop. i didn’t know wtf was happening and then i just froze. i don’t remember what happened next. then when i was 14 this boy, who is my friend, would grab my boobs and slap my ass every time he saw me. which was everyday and even when i told him to stop he wouldn’t. and he also pinned me down and kissed me and locked me in a room and shut the lights off and pinned me to the bed and started grinding on me and touching my boobs and trying to kiss me and trying to unbutton my jeans. he touched me through my pants. it didn’t last long cause i head butted him. but the entire time this was happening i was screaming for him to stop and he wouldn’t. i was so scared. i never thought about it much. i kinda repressed it but then today my best friend told me that she was sexually assaulted by her other best friend’s dad it started bringing back all the memories and I was completely frozen I couldn’t stop thinking about it and I’m having a lot of anxiety right now I don’t know what to do. i feel like it’s my fault for not trying harder to make it stop. is this sexual assault? this is my fault. and i feel bad for my friend cause she won’t let me tell anyone about her experience

Update

i messages the boy and told him we can’t be friends. i explained how what he did affected me. he said sorry. it still doesn’t feel right
