I was drunk and he wasn’t

So last night this guy wanted to hang out. I’m 17 and he’s 19. I hadn’t met him in person but I had seen him around and we had been snap chatting for awhile. Anyways, I ended up sneaking him into my room at around 2 am and we started drinking. Long story short I ended up drinking way more than he did and he was basically sober and I was gone. I was blacking out here and there and had absolutely no control over my body. I remember him moving me and it felt like my body was dead because of how unable to move i was. I remember making out and then him taking off my pants and then I blacked out. When I became aware again he was fingering me. My friends are really upset because they think he took advantage of me. He apologized for the whole thing and he feels bad about it, but should I be concerned that this happened? Do you think I should stop seeing him? Or do u think if he had the opportunity he’d do it again? All last night was a complete blur and I honestly don’t know how to feel about the situation right now.
