Here it is:

Met this girl on a dating app. She came right out and said she would be up for a hook up only.

We go out and I take her back to my place. My roommate and three of his male friends are there but leave shortly. She is quiet the whole time. I ask her if anything is wrong while the six of us are talking. She says no and fiddles with her phone.

I ask her to watch a movie. She says ok. She starts talking about how she needs to leave when the movies starts. I joke with her about her promise. She laughs, I laugh. I move in to make out with her. She isn't into it at first. I ask her if she is ok. She says she is ok. She fiddles with her phone a bit (reception is really bad in my apartment/area). I gently take it from her and put it down. She seems ok with this. She smiles. I move in and try to start things again. She is into it.

Sex happens. After, I go to take a shower and I come out and she is gone. My back door is open. I drove so she doesn't have a car.

About 20 minutes later, the police come by and arrest me.

Apparently, she says she felt unsafe and I raped her and when I left to take a shower, she "fled" the house and went to the neighbors to call 911.

They found her underwear in my house and they said it had a bit of blood in it. I don't know how that could have happened but it could have been there before. The sex wasn't rough.

I am not sure where to go from here. They said I'd be assigned an public defender because I am so poor.

I didn't sign anything or admit to anything. I just told them it didn't happen like whatever she claimed.

They won't tell me if the rape kit came back positive for force or not and they won't tell me all of what she said.

WTF happened? How do I not to go to jail forever because of some crazy sensitive person who read the situation wrong? If she had told me no at all I would have stopped or asked me to take her home, I would have.
