A guy thinks he raped me

Many years ago, when I was 20F, I had a crush on my bestie’s cousin (29M). I had known him from my friend’s family gatherings, but we didn’t start getting close until we worked together and I would sometimes give him a ride home since he lived a few minutes away from me. I knew he was flirty with me, especially knowing I was newly single. We shared blunts a few times and then we had to address the sexual chemistry. The first time was quick… but from talking, he knew I liked things rough *ahem* like forced? (this was before discovering that cnc was a kink, I just thought I was broken). So the second time I come in after giving him a lift, we start fucking and I playfully (I *thought* it was playful) said “Nooo stop 🥺” and he looks at my face and immediately pulls out, starts apologizing thinking he forced himself onto me. I tell him it’s okay, I liked it, I wasn’t actually wanting him to stop. But he was full crashing and I was like “I’m fine, it’s okay. I’m just gonna go home.” He cried to his cousin (my best friend) who told me he was sorry, I told her that it’s fine, it wasn’t like that. And I think they just thought I was accepting the victimization or something since she knows I have a SA history... I was met with pitiful gazes. To this day, if he sees me react to something on social media, he will reach out and message me and say how sorry he is and I just don’t know what to say other than “it’s okay, I didn’t think of it as rape”. And I don’t want to unfriend him/block him because I feel like he would actually think I hated him and feel even more guilty. I was so young and dumb and uneducated on proper/safe kink exploration lol. Please take it easy on me, I genuinely don’t know what to do.
