Was I actually SAd?

So this girl was my best friend since we were 15 but this happened last year when she was 20 and I was 21. Her and i were very very close and even had a sexual relationship when we met. She always said she was straight but would constantly try to hook up with me knowing I was bisexual. After years of friendship she betrayed me and we lost contact, then when i she was 19 and i was 20 she started working at the same place as me and we became friends again but not as before. One night we went out drinking and i got very very drunk and so did she so i invited her to stay the night so she wouldn’t drink and drive.

When we got to my house i got very sick from drinking then i went into the bedroom but i even brought the trash can in because i was very nauseous. after getting into bed with her it was cold so i asked her to get her feet close to mine cause mine were freezing. I forgot to mention but i had a boyfriend at the moment so i was in no way interested in her. After I she gets closer to me she suddenly sat up pulled my underwear down and started eating me out. I was extremely confused and the room was spinning since i was still nauseous and I was also tired so i was slipping in and out of consciousness. i was shocked and didn’t know what to do so after just laying there i pretended to finish so she would stop. And after I think i asked her why she did that and she said she didn’t know that she was just really horny, then she asked me if i liked it and i said i didn’t know since i was so drunk, then she said she was straight but she was attracted to me, after that we fell asleep and thats that. I had to work with her for months after that pretending nothing happened. Then she told me she was actually diagnosed as a nymphomaniac, but idk how to feel. I hated what happened but I feel like it was my fault for not stopping her or not saying no. I tried telling someone close to me and he said it was hot and i was just very disturbed and upset. Was this considered SA?
