Was I sexually assaulted?

Hi this is my first time posting here and I can’t get the thought of what happened out of my head so please go easy on me lol.

I (23F) went out on a date with a guy (23-24M (I don’t remember his age)) that I knew from high school a few months ago and long story short we ended up having sex later on that night and it was the most uncomfortable and painful experience I’ve ever had. Here’s how it happened:

We first went on a walk on a trail not too far from his place and we were catching up on old times and he starts getting handsy like wanting to hold hands, grab my waist and hug me and literally find other ways to keep his hands on me. I had told him that I wasn’t really comfortable or used to physical affection but he still tried different ways to touch me essentially. We then made out for a bit and I feel his hands go under my coat (this was during the colder season) and grab my waist and then my ass as we’re kissing. He then asks me if “we can take this back to his place” and I feel him caressing my boob. I got very uncomfortable with his hand placement and I was too scared to say no because I didn’t know what he would’ve done if I had rejected him. So I said yes and we go back to his place.

We’re at his place at this point and he brings me to his bedroom, turns off the lights and we start undressing and having sex. I told him that I was a virgin beforehand and he said ok I’ll be gentle and while we were having sex he was very rough. I had told him repeatedly to stop cuz it hurt too much and he either ignored me or he stopped for a bit and then continued fucking me. It got to the point where he was so rough and it was so painful that I ended up dissociating and blacking out while he’s still fucking me. After coming back to my senses I’ve lost recollection of some memories and track of time and remember that I’m at this man’s house laying naked next to him on his bed and I needed to get away from him. I tried going to the bathroom but he ended up following me to his bathroom and he teased me a bit and then he starts making out with me as he pushes me against the wall and kisses and touches my boobs and I just froze at that point. He also kept persuading me to be his girlfriend saying how he’ll take care of me but I had already made up my mind about not pursuing a relationship with him. He then dropped me off at my place and later on he texted me about what happened and I told him I was not comfortable being his girlfriend and un-added and blocked him on all socials.

Months after this happened I have been going through so much from dealing with the pain in my thighs and private parts right after it happened to being haunted by the memory every single day and feeling like it’s my fault that this happened. I’ve always wondered if what i went through was assault but it didn’t feel violent enough to categorize it as such (I’m also on the spectrum so it’s hard to pinpoint anything). I’ve thought of going to see a therapist about it but at the moment I don’t have the money or time as I’m now in school and I’m also working. I can’t stop thinking about it and at this point I’m exhausted and want to move on but I feel mentally stuck. I’m hoping to get some advise about this and how to move on or just know that I’m not alone in this cuz I’ve basically dealt with this alone and I’m tired of it. My bad for the long text, if you made it to the end thank you sm for reading this and hearing me out :).
