TLDR; Threw a Halloween party with friends. One of them was drunk/shrooming and spent the night feeling me up, groping me, and joked about pushing my boundaries after I repeatedly asked her to stop. Later spoke to her about it, she says she has no recollection of this. Me and other friends don't believe her. Still trying to work out how I feel about everything.

Some background: My friend, we'll call her V - has been one of my closest friends since we met years back as young kids with dumb jobs. The other friend, X - became friends with V when they worked together a few years back. X and I eventually became mutual friends. The three of us got a place together and we've been chill ever since.

So the weekend of Halloween we threw a house party and had a bunch of friends over. Everyone is 25 so it wasn't a rager, but plenty of alcohol and food and an impeccably decorated house (we worked hard on that shit). So the night starts off normal, everyone is either drinking or high or on whatever assortment of things they're doing, but it's very chill. Me and a friend notice that X has gotten a little toasted and so we start telling her to go eat, get water; the usual drunk management. Eventually she comes to where we're sitting and she sits in a chair next to me and lifts her legs and puts them on mine. I push them off and tell her not to do that, and that I don't want anyone on me. But she proceeds to do it again and then eventually comes close to hug me and also rubs my thighs and I push her off and tell her again, I don't want anyone on me. I chalk it up to her being an affectionate drunk and go on with the night.

Later on she comes up behind me when I'm sitting and wraps her arms around my neck and starts talking to me about V and her fwb. X is complaining about them which I don't get and also don't care about and politely shove her off me and tell her not to be on me...again.

There's a few other times throughout the night where she tries to put her legs on me and intertwine them with mine, and rub my legs and I keep telling her to cut it out. Eventually I start paying attention to her behavior with everyone else in the house and notice that she's not doing this to anyone else but me. And it's odd.

Later towards the end of the night, me, X, and V are sitting on the couch with a couple of other people and I'm in the corner of the couch between X and a mutual friend of her and V's. I've never met the girl. X proceeds to put her elbow in my lap to lay on me and hug on me and starts rubbing on my upper inner thigh. I immediately yell that I'm feeling claustrophobic and to get off me and the friend jokes about me having boundaries. Then X says, "Oh yeah, but she's not as affectionate, but I can push her boundaries." I'm fucking grossed out and also don't even know how to comprehend what is happening. I get away from her and stay away from her the rest of the night. After we get everyone out, me X and V are sitting in the living room (I'm on the other side of the room in a lounge chair) and we talk about the night. There's no mention of what happened.

I'm cool with X over the next couple of days (we watch a show in the living room), but I'm always staying physically far away from her. Eventually I start processing what happened and I realize how I feel and how uncomfortable I am with what happened. Especially the gross comment about pushing my boundaries. I was also shocked because I've never had this experience with a woman. With men? Of course. But I've never had a woman violate my body and boundaries that way. So I talk to V about it and she can't believe. Neither of us can, really. Because X is a really sweet person and she's genuinely the last person you could even imagine doing some shit like that. She's never even behaved that way before.

I eventually I text her and explain that I want to sit down and talk about what happened at the party and she gets anxious and asks, so I tell her. In her response she says, "Like I remember everything that happened as it did but I've already forgotten most everything from the last couple days."

Wtf does that even mean?

So the next day we sit down and I tell her everything that happened. She looks shocked and apologizes and tells me that she doesn't remember any of that and doesn't know where it came from. I asked her where this behavior came from because it was only me that experienced it and she said she had no idea. X goes on to say all the right things about respecting my boundaries and what can she do to make sure I feel comfortable, etc etc. She says everything you want someone to say when they've fucked up.

The conversation really didn't go anywhere after that and I told her I needed a physical bubble of space and to sort out how I felt about things. But the thing is I don't believe X and neither does anyone else that's aware of the situation. We all believe that she remembers what happened and is lying to save face.

The reason I don't believe her is that the week after the party, besides that one evening watching tv - X and I didn't communicate and we normally chat through text throughout the week if we don't see each other at home in passing. It was radio silent. She also wasn't talking to V really either. So it felt like she knew something was wrong and was avoiding the situation. Also, her response to our conversation felt a little too...clean? Like she knew to prepare for this, or knew it was coming or something. Our conversation felt hollow and I didn't feel any different after we talked.

Secondly, I've wondered for months if X has a crush on me. She often stands or sits or walks too close to me and is in my personal bubble too much. I've literally run into her when we're out and about because I turn and she's right fucking there. I've told her this but she still seems to not get that she's often too close.

I also generally avoid any close physical contact with her, which is why I think she made that drunk comment about me being unaffectionate. I'm actually very much a teddy bear and love affection, but months ago - and I don't remember what sparked it - but at some point I would feel really uncomfortable anytime X was too close to me. I felt weird whenever there any physical contact, even like jokingly touching me or patting me on the back or anything. When I spoke to my therapist about this, she said that it seemed like maybe my body was warning me because I could sense something before I could articulate it.

Also X is sort of a late bloomer; she had some serious medical issues in her early 20s that took over her life and she only recently moved out of her parents' home so it's really her first time living her life fully. From what we know, she's never dated. She's never once mentioned exes, bfs, gfs, nothing. She will comment on a hot guy in a movie or things like that, but when V and I are talking about our dating lives, exes, past relationships, etc - X never has anything to say about her own. She's mentioned sex one in passing but that's it. She also dresses in an ambiguous rocker girl style that people often mistake as queer.

After the convo, X spent four days in her room. Things have eventually thawed out and we've chatted here and there. And that's felt okay enough. But she asked about going to see a movie and I told her I'd think about it. She also mentioned going to a show to see a band we both like. It's like she just wants things to go back to normal (understandably) but I'm like...our conversation didn't go anywhere. There was no resolution, nothing. And so we're just supposed to move on from it?

Part of me feels like I'm making too big a deal of this. Part of me is wondering if she really doesn't remember and maybe I'm still just angry because I didn't get an answer or resolution. Part of me wants to move out because I don't want to share a space with her anymore.

I'm feeling all mixed up and I don't know how to move forward with this. Does anyone have any advice, or words, something or anything to help me with processing this or dealing with her or similar experiences and how you dealt with it? Because I don't think X is a bad person, she's a really sweet person - and I don't want her to feel shitty about fucking up. But I also don't know if she's lying to me.
