I [20M] think my gf [19F] SA'd me, how do I move forward
Every Wednesday since the latest season of survior aired, me and my buddy have a tradition where we go to his dorm and we have 3-4 beers while watching the new episode. I usually leave feeling pretty buzzed but never anything more, however last night however I had brought some whiskey and we each had two shots along with our normal amount of beers. I had let my gf take a nap in my dorm while I was out and when I came back I just wanted to hop on the game for a bit and knock out. After playing for a bit started getting touchy and gave me head while I was playing for a bit before laying back down. After I finished up the level I told her something along the lines of "man I really shouldn't be playing tactical games when I'm drunk" and then she said
"You're drunk?" And I said "yeah I had some shots with my buddy and our beers." After that I told her I was tired so I turn off the game and rolled over to go to bed. However she kept touching me and one thing lead to another and she ended up on top of me. After a bit though I told her I was tired and asked her to stop which she did. She then apologized and left and when I woke up this morning she had sent like 5 messages saying how guilty she felt and stuff along those lines. I don't fault her for the first part because she didn't know I was drunk but it's after the fact that she continued knowing I was drunk and tired that's messing with me. We’ve been together for 2 1/2 years and I love her so much, but it doesn’t feel the same after that, Idk i’m not sure how to explain. How do I handle this with her and where do we go from here?
TLDR: My gf might have sexually assaulted me and I wondering where our relationship goes from here
