i think i was sexually assaulted by a friend, i need advice

i’ve been fiends with this guy for three years, he was always really respectful never tried to touch me so I’ve always trusted him. i was out with him and he asked me if i wanted to go to the beach with him and his friends i asked my mom for permission because she has met him several times and she also trusted him so she said yes, when they picked me up they told me that they will be drinking and asked if i would drink with them i said no(i also don’t drink so i have no tolerance), later that night they were drinking and one of the girls that was with us kept telling me to drink so i was like okay its only once what could happen! i drank only one cup and i got drunk. i could stand up i kept falling and crying the first thing the girl that poured me the cup and her boyfriend said was “oh shes faking it” and ignored me, my friend he started making me drink water and stuff and then he was like do you want to go on a walk? i said ok (all of this happened while we were at the hotel) he was helping me not fall and stuff and then he walked me down to the beach and i just sat on a sun bed and fell asleep, i woke up 4 hours later and he was being kinda distant? i was really scared for some reason i felt like there was something wrong. i texted my other friend i was telling them that i got drunk and now i woke up but something feels weird, he noticed me texting my friend and got mad and started telling me why are you telling people that you got drunk whole you’re with me they’re gonna think that something happened!!! and he started naming my

closest friends telling me i shouldn’t tell them. i was like what is he trying to hide so bad?? and then he stopped talking to me for a couple of hours until we were at the swimming pool he was asking me if i remember anything, i was telling him what i remembered and he kept saying is that the only thing you remember??? are you sure you didn’t forget something, i was begging him for an hour to tell me what happened and he finally did he was like i kissed you, you were just staring at me and we kissed. i didn’t say anything because i started just feeling like shit and i was just waiting until i could go home. while we were on the way back the car was really cramped and i was next to him i was falling asleep and he kissed me again. i kept acting like i was asleep and when we arrived and i got home i was like wtf was that in the car? he started saying that i wanted it and that i leaned in for it, and that we should talk about what happened face to face so we went out he kept going on about how everyone else thought i wasn’t drunk and i was doing all of this just to make a move on him, that i wanted it and stuff like that so i started convincing myself that maybe thats what i wanted?? and that i shouldn’t tell anyone about this because they would call him an assaulter which he thinks he isn’t. this happened back in july i kept ignoring it until now, last week my friend asked me about it and i told her everything and she told me that whay happened wasn’t okay.

i need advice on what to say to him because he texts me from time to time, and because all of my friends are friends with him, i also can’t tell my parents. i just want to know what i should do to kind of make the situation better
