Sexual assault or my fault?

So the past weekend i went over to a guy’s place to drink. I dont usually do this because i dont really drink nor really trust guys. But i went bc i was having a hard time with my breakup and wanted to drink to forget about it that night. I went over there knowing that this guy has been asking for sex, but i made sure to let him know before that i didnt want to. And when i arrived, he was already drunk, trying to make moves. Im still saying no, im still pulling his hands off of me. Usually i leave in situations like this, or try to avoid situations like this. But i was really upset and all i could think about this is also a part of moving on. So after i started to get drunk too, i let him reached his hands under my shirt and groped my breasts. At this point, im not saying no anymore im not pulling him away. I felt dead inside and nothing mattered anymore. Of course, he was trying to get some more out of it, at that point that’s when i got up and left. I still felt violated bc i was saying no the whole night, i was silent, i didnt say yes, when he went under my shirt.
