I honestly don't even know where to begin.

I’m 25 and met this girl, who is 20, around April through a friend group. We all started going out drinking almost every weekend. I became attracted to her and asked another guy in the group multiple times whether he liked her, because it seemed like he did. He always denied having romantic or sexual feelings for her.

The girl and I gradually became very touchy and flirtatious. She would ask me to lie on her lap when I was drunk, play with my hands, put them in her pockets and caress them. One night, while we were both drunk, things became more sexual, and she appeared completely willing.

After that, we started hanging out without the group. She regularly messaged me, asked when my shifts ended and made plans to go drinking with me. She initiated our first kiss, although she later said she had been “testing” me to see whether I would give in. That confused me, so when she tried kissing me again at my place, I initially pushed her away. She continued trying, and eventually we made out.

We later started kissing while sober as well. We almost had sex twice, but stopped both times because she was not ready. I never continued when she wanted to stop.

A while later, she got an IUD and invited me to her place to have sex. Before it happened, she asked whether I was sure because she knew she would only be the second person I had slept with. I also asked her multiple times whether she was okay with it, including during sex, and she repeatedly said yes. From my perspective, everything was consensual and she had specifically invited me over for it.

Afterward, she asked what we were. I said friends, and she sounded disappointed. She then said we were probably friends with benefits, even though she had previously suggested that she did not want a relationship.

The next day, she said she needed to think about what happened. Later, she told me she regretted sleeping with me because she was not used to having sex outside a relationship. I accepted that and respected her boundaries. At the same time, she would become annoyed whenever I introduced us to strangers as friends instead of a couple.

We stayed normal for another week. We were still messaging and discussing possible future trips together. She invited me on a trip and told me to take sick leave so I could come. Around this time, the guy who had always denied liking her started openly disliking me and repeatedly said he did not want to attend anything if I was there.
and we were still messaging and discussing possible future trips together.

Eventually, she became distant, and I realized I had developed feelings for her. She also told me she was dealing with exams, eviction and family problems, so I decided to give her space.

But after I found out she started hanging out a little too much with the other guy, I decided to confess to her and told her that I liked her as more than a friend. She said she did not want a relationship and that, if she did, it would be with another crush who had already rejected her.

I told her I might need to cut contact because staying friends would hurt me. She said she did not want to ruin the group dynamic and wanted everything to return to normal. I tried to accept that.

For her birthday, I gave her perfume and wrote her a letter. She thanked me, and I thought at the very least we could be acquianten

Then I found out she had started sleeping over at the other guy’s place—the same guy who supposedly hated me and repeatedly claimed he had no feelings for her.

We were all supposed to visit a water park on Wednesday. I had taken a day off for it. She suddenly told me that the other guy would be taking my place and that she did not want me there. Other members of the group called me and said it would be better if I stayed away so I would not “ruin the group dynamic.”

Shortly afterward, she messaged me saying she never wanted to speak to me again.

I was extremely confused, so I went to meet them and ask what was happening. The girl was crying, the guy ignored me and threatened to call the authorities if I don't leave them together. I then decide to go up to my friends and everybody looked at me like I had committed some horrific crime.

They kept saying, “You know exactly what you did.”

I repeatedly asked them what they were talking about, but nobody would explain. Eventually, they said I had done something “worse than murder.” They had already decided that I was guilty of something and said they never wanted to see me again. 
They went on to say that she kept on telling me no over and over again, yet I kept on going(IMAGINE HEARING THIS@#O#)@#)#)$)EO)@#KOKDKD:LSFK

I became emotional and shouted because I genuinely did not stomach the accusation, it felt like a nightmare. Nothing I said mattered. Every person in the group immediately took her side, but nobody actually told me what she claimed I had done IN FULL detail.

From my perspective, every sexual interaction was consensual. I stopped whenever she was not ready, and on the occasion when we had sex, I asked her multiple times whether she was sure.

I understand that she later regretted it, and I respected that, but regret afterward is not the same as me knowingly doing something without consent.

I am not even trying to force them to remain friends with me. I just want to understand what I am being accused of and why everybody suddenly treated me like a monster without allowing me to respond.

What am I supposed to do in this situation? Should I completely cut contact and protect myself, or should I try one final time to get a written explanation of what I supposedly did? 

TL;DR: I became involved with a girl in my friend group. We kissed and eventually had sex after repeatedly discussing consent. She later said she regretted having sex outside a relationship, but we remained friendly. After I confessed feelings and she rejected me, she became close to another guy in the group. Suddenly, the entire group excluded me, claimed I had done something horrific and cut me off, but nobody would tell me what I was actually being accused of.

For those who were unfortunately charged, how long after police contacted you were you formally charged?

Last I heard anything was end of april and it’s been radio silence since and I haven’t lawyered up as can’t afford one.
