Happy birthday

So it's my birthday and last night a group of us went to my friend *Scott's house. It was me, my best friend *Marie, Scott and my boyfriend (will we're on a break for mental health reasons) anyway we all got super drunk and smoked a bunch of weed (we live in Canada).

The boys took sleeping bags on the floor and the girls took the bed. Except Scott didn't take the floor. He was still on the bed and I had my legs on him when I fell asleep. I vaguely remember him rubbing them but I was way too stoned to understand what was happening. Anyway later on in the night I'm in and out of consciousness but I remember him moving up my legs and laying beside me. I wasn't fully awake until I felt him pushing inside of me and then I was in shock and I just laid there trying to figure out what was happening. He tugged my hair and shit. I looked at my boyfriend and snapped out of it enough to push Scott away. I didn't want to ruin the night so I pretended to still be asleep. I grabbed my boyfriend's leg and shook him hoping he'd wake up but he didn't.

I rolled over to the edge of the bed and faced Scott still pretending to be asleep. He stopped for a second then I felt his hand wipe my hair out of my face and then across my lips. I don't know what to do. Scott and I were fwb once and it went bad. We didn't talk for a year until last May. I don't want to lose the friendship he's always been there for me..i told my bf but I haven't told anyone else because I don't know what to do. Should I tell someone? Should I tell my best friend? Is there any advice? I'm so lost
