Might be a bit of a long read, but this has been qeighing heavy on me, and I want to provide as much context as possible.
Context: I am at a big uni-party with some friends. I know a lot of different people around uni, so i bounce between friends for most of the night, dancing with a lot of different groups of people. I have a female friend (we'll call her A) there with whom i have a bunch of mutual friends, someone who i get along great with and who is being physocally affectionate towards me during the party( tight hugs, playful pushes, buys me a drink). She has a friend with her (B) who tries to flirt very aggressively with me by dragging me to the dancefloor, buying me shots and sweettalking. It quickly becomes a bother to me, so whenever B tries to flirt, i seek out A or some other friends so that I'm not alone with B. At one point while going between friend groups, I make eye-contact with a third person (C) who I don't know, but who seems impressed that I can do a little salsa. I bust a salsa move with her and then leave, we don't touch or anything, just a fun little dance and we are both on our way.
After downing a few drinks with various friends, I dance with A and a couple of our mutual friends where we all are hugging each other, and after that I end up just me and A. At one point we end up with her arms around my shoulders, my hands by her hips, but she is looking away and doesn't seem into it, so i back off and dance as I have been dping with all my other friends. I then go with her to a circle of people where I only know A and one other person, and C is there too. When i join the circle initially, C steps right in front of me with her back turned and keeps dancing. I think it's weird and step to the side and keep dancing. Then B comes over to the circle, and it's clear that she is trying to get rid of a guy who is being a bit too persuasive, so she reaches her hand out to me to drag her in. But as i try to reach her, C steps in directly in front of me again, pushing my arm away, and keeps dancing directly in front of me. There is a few seconds where I am in shock of whats going on, still dancing, but my mind freezes as I am trying to figure out why C is doing this. But when this happens, the only other guy in the circle comes up to me and tells me not to force myself into their friend group like that. I'm shocked, tell him I am not trying to be weird and that I know A, but thank him for letting me know, and then I leave. In shock, I go to a friend and tell them that I am worried I did something wrong, but they just dismiss the guy as a jackass. I don't necessarily see it that way, I think it's just a misunderstanding, and he was being a good friend to the girls. At a later point C comes up to me and a friend and ask for cigarettes, and then makes out with some guy on a bench, so I think maybe it isn't that serious. Later one of my friends gets seriously ill from alcohol, and i ask another friend for help, the guy from the circle is there and gives me a nod as i leave.
I want to know if there was a point where i misstepped? I can see how to him, if he looks over and sees C standing in front of me like that, it may read as my trying to grind on her, even though I didn't mean to. I also wonder if maybe i have made A more uncomfortable than I realised, and she went to that circle to get away from me. Now I will fully admit that I am not always the best at reading body language, and I was quite drunk, but that doesn't excuse anything. If I crossed a line then I crossed a line, and I take full responsibility for that. I just have a hard time figuring out what happened, especially because I didn't intend to cause any harm, and I am genuinely anxious to go to the next prties now. I have been reading about body language, social cues, SH, SA and consent, but it just blurs things for me even more, and makes me more anxious.
Any and all input on this would be greatly appreciated. I don't want anything like this to happen again.
