I feel like shit

Was it even rape? Did I ruin his life? Is it my fault?

Backstory it happened when I was in college closed campus. I was 18 he was 16 I and way smaller.

So it started with a game of truth or dare and we were dared to kiss each other. And at the time we both were drunk and high. We made out just kissing no touching or anything. Then later on that day when we were sober we were walking and talking he pressured me in to sucking his member. That night he said he felt bad and wanted to walk and talk about it. And as we were walking I realized he was taking me out of where we were allowed to be. I asked him where we were going and he said he wanted more and them I saw some of my friends and tried to just join that group of people they told me to go and that they were going to tell my bf at the time that I was cheating. Then the guy picked me up and took me out of bounds I tried to go back like lol nah I have to go to my dorm my roommate texted me and needs help with something. That didn't work then we sat in the back of a truck together and he wouldn't let me out so I sat there till I gave up things happened and I was scared it hurt so bad everything hurt. Then the next day I was out smoking a cigarette and he asked if we could do it again. I got scandal went back to my dorm. I then told my roommate about it and she told me to tell security she went with me I didn't press charges but he was kicked out of school. I just dont know anymore should I unblock him and apologize or was I right? What the hell even happened? This happened almost 3 years ago and I am still questioning myself about it?
