Was I Raped?

I'm 16. In the summer, my parents went away and I threw a party in their house (yeah, I know). There was a boy coming that I liked and had sort of been flirty with, but I had always made it clear to him that I wasn't going to be so someone that he could use and throw away, and I wouldn't do anything with him on the first date, even though we had sexted a couple times. As the night went on, I got increasingly more drunk. I was falling over, flirting with him, holding onto him, and doing things that made it seem like I was interested in him. At some point, I went up to him and asked if he wanted to go upstairs, I never said that I wanted to have sex. When we got up there, he started kissing me, and took my shirt and my bra off and was just touching me everywhere. At some point I just fell onto my back on the bed and felt him taking off my pants. I didn't fight back or scream, I kind of just froze. And I know I never said I wanted to have sex with him. I didn't want it to happen and I think about it all the time, and I'm not sure about what to do.
