was this assault

Ok so on Friday night I decided to go out with my friends. We went to a frat and I was getting drinks for myself, had maybe 4 or 5 shots total, nothing unusual for me, I'm usual fine with drinking. I had eaten dinner prior to this, and also I hadn't pregamed at all, so I was only drinking at the party. I have some suspicions that I was roofied because of how drunk I got/how much I blacked out afterward.

I met this guy and I ended up following him back to this apartment. He's older than me and in the frat. I have no memory of how we got back to the apartment, like whether we walked the entire way or called an Uber. I do remember I was so drunk and he was carrying me at one point. At another point I stopped to sit down, we were still on the campus, and he pulls out his dick and I just give him head for like a few seconds, I don't even know why. I wasn't even attracted to him to be honest. And I'm so confused as to why I left my friends. I have never gone home with a random guy before - it's so unlike me to do. I'm usually so cautious and guarded.

When we get to his apartment it all becomes even more of a blur. Our clothes come off and he's on top of me, and I feel a sharp pain as he tries to shove his dick into me. I'm a virgin - I've never even let a guy take off my underwear before. I don't think it goes all the way in, or even at all. Maybe it did, maybe it didn't, I'm unclear. I don't think there was blood though, so maybe that's a sign it didn't go in.

At this point my friend is super worried and calls me and tells me to get myself an Uber immediately and leave, so I do. If it hadn't been for her I don't think I would have managed to leave and get home. I was so out of it, its scary to think about what else could have happened. She called me right when he was trying to have sex with me and when I told him I was calling and Uber and had to go he stopped.

In the Uber, I remember throwing up. I have never thrown up before from drinking - this is another reason why I suspect that my drink was spiked. I get back to my dorm and my friend meets me and takes me to my room - however I only discover this afterward. I have no recollection of meeting up with her after the Uber - I guess I had completely blacked out by then.

The day after he DMs me Are you okay? And he claims he blacked out and wants to know what happened. He claims he only remembers seeing me at the party and then waking up in his bedroom and finding some of my things. He says he wants to make sure I felt safe the whole time and that he would never want to make a woman feel uncomfortable.

I told him to not worry about it, "nothing really happened." Because I don't want to cause any trouble, I just want to forget it ever happened and move on. I don't know if I fully believe he was totally blacked out the entire time, and I don't think it excuses his actions.

But I am also just really confused. Does this qualify as sexual assault? Have I been assaulted? I don't think he's a bad guy, or maybe he only reached out afterward because he's worried I'll get him into trouble and wants to clean this mess up. I don't want to think of myself as a victim either.

I don't think I've fully processed everything and I don't really know what to do about it. Where do I go from here?
