is this sexual assault ??

so almost 2 years ago i feel i was sexually assaulted i don’t know if it could be considered that. so i was in a club and we had been leaving a event at night so one of the members that i looked up to and saw as a role model asked me can he sit next to me on the bus i said sure then he says “i’m going to touch you.” and i make direct eye contact and said no firmly not in any type of playful manner so we get on the bus and me think he understood how i felt i let him sit next to me.

the lights finally go off on the bus and he keeps touching my thigh and he pulls at my belt buckle so i stop him and tell him no. i had to whisper it cause there were 13 other people on the bus including our advisor so he keeps trying to get his hands on my pants and trying to convince me to let him finger me so finally i give in because i was overwhelmed and i didn’t want him to say anything bad about me it turns out someone kinda recorded and the two girls behind us could here me saying no and stop it was so uncomfortable and it hurt so much.

so the next day one of my close friends text me and says something about the situation so my friend says “so you let him” and i tell him the story and he begs me to come out of class and explains me to how that’s sexual assault. i was thinking it was but since sexual assault/sexual abuse/ sexual harassment/ rape aren’t really topics were taught about i didn’t know how to label it. then 2 females go around telling everyone i’m fishy and i let him and i’m easy.

i’ve never told an adult about this and it’s going to have been 2 years on september 29 and what makes this worse last summer he lied and told his coworkers that are also some of my friends that i have him oral sex and he fingered me and i was so hurt when my bestfriend told me.

to top that he’s still in my life and he’s one of my father’s employees. my bestfriend and our other close friends look at him differently and they see him basically everyday at work. this still somewhat effects me till this day

can someone please explain if this was sexual assault or not
