I'm going to be vague, because friends of mine who know what's going on also browse Reddit.

I've had a very close friend of mine, who's a woman, for about a year now. We were sexually active for a long time, indulged in a threesome together, went out partying together, and in general it was a good time. I was there with her through her divorce, and she was next to me after a bad break-up.

So, she started seeing a guy that she had known from childhood. No worries, because as far as I knew we were just friends that had casual sex every now and then, and if she needed to date this guy to get over her ex-husband, I would support her in that endeavor.

Now, the girl, we'll call her Kat, and the guy, we'll call him Rick - are dating for a while. I meet him, we hit it off great, and every now and then we all go and hang out together. Nothing weird, but Rick doesn't know about mine and Kat's previous intimacy, and I never bring it up because I don't want to spoil anything that's going on. She's acting like she's very happy at this point in time, so I don't try to unnecessarily rock the boat. Plus, she could be annoying sometimes, texting me 20 times in a row before I get the opportunity to respond, and most of this ceases when they started dating.

So, one night we all decide to go out. It's me, Kat, Rick, and my friend Abe. We go out to a bar and after being there for an hour, Kat receives a text message from a girlfriend named Michelle, whom I had hooked up with some years ago. She wants us to come to the bar she's at. So, we all pack up and leave - and head to this other venue. Michelle and I are flirting at the bar, we haven't seen each other in a couple of years but have been keeping touch sporadically via Facebook. She's engaged, but telling me that he's been cheating on her and she's planning on getting revenge on him for it. So, I think whatever, not going to worry about it. I wasn't, at this point, really interested in hooking up with someone I've already been with before (who wasn't that good as far as I can remember) involved in such drama.

So, over the next few hours we're all drinking, doing shots, in general having fun. Michelle suggests we leave and go to another bar - so we all follow suit. Abe ends up going home because he has to get up and work tomorrow, and since he was my ride, I end up hopping in the car with Michelle. We kiss a bit, and she started looking pretty good as the night dragged on.

We get to this other bar, have a few drinks, and then Michelle suggests that she and I go back to her place. So, we say goodbye to Rick and Kat, and we head out to Michelle's apartment. We get there, light up a joint, drink some wine, and we're just kind of laughing, talking about the past, in general having a good time.

Then we receive a phone call from Kat. She's hysterical, crying and screaming into the phone about how Rick was drunk and just tried to kill her by running the car into a passing train. He had left the scene of their totaled vehicle, and she didn't want to call the cops because they were both drunk - and he's an ex-convict. She manages to find a ride over to Michelle's apartment (about 30 minutes from where she was).

At this point both Michelle and I are trying to console Kat. Nothing much is working, so she smokes some pot and has a few glasses of wine. I'm tired, so I tell Michelle that I'm going to pass out in her bed. Well, Kat passes out on the couch - and Michelle gets on the phone with her fiance and they apparently work everything out. So, she comes in, wakes me up, tells me I have to leave. I was pissed, too be honest, because I was wasted and had no ride home - it was her idea for me to come here.

I didn't put up any resistance, but Michelle informs Kat that she's taking me home. Kat says if I'm leaving then she's coming with me. So, Michelle carries Kat and I back to my house. We go inside, she tells me she's just going to crash with me for the night. She had done it on several occasions, so I wasn't really worried about it. She asked me for some clothes to sleep in, so I give them to her, I have one more beer, then brush my teeth and we go to bed.

We wake up the next morning, smoke some pot, watch some funny videos and hang out. Not really a big deal. She reconciles with her boyfriend, and then he comes and picks her up a few hours later.

Fast forward to Thursday of that week (it was a Saturday night when we went out, a Sunday morning when she went home). She texts me saying that she remembers 'something' happening between us. I told her that nothing happened, but if she'd like to call and talk about the series of events as far as I remembered it, I'd be happy to oblige. We talked on the phone a few days later, she had pretty much been ignoring me - and I was probably being overly paranoid. I thought everything was resolved. I told her that nothing happened, that I gave her clothes to wear, I brushed my teeth, and we went to bed. She said she remembers waking up with me naked on top of her, and I note that we woke up fully clothed. It pretty much ends there, or so I thought.

This past Sunday morning, at 3:00 AM - she sends me a text message saying that she knows something happened, that I should just admit it, she's going to tell her (now husband) that I tried to have sex with her, etc. etc. I respond that nothing happened, and suggest that she dreamed it. We were both very intoxicated, but there's no possible way I'd have had any kind of sexual contact with someone and NOT remembered. It's never happened before, and I've had significantly more to drink/smoke in a shorter time frame than that night.

She basically tells me we can no longer be friends, and I've been partially paranoid that she'll go to the police - because she's just that kind of person.

Now, here are a few things to note:

The time between the first accusation and the second was a period of four months. She sends me text messages like, "you're my only friend, I love you", "I need to come have some hangout time with my best bro", she texts me intimate details of her married life, even goes so far as to threaten suicide one night because of how unhappy she is in her new marriage.. I talked her out of it. Despite her emotional and mental issues, I stuck in there, because I thought she was a good person. Obviously I was wrong.

So, here's what I've done: my father is an attorney, and at his suggestion I decided to print out all of our text-message and Facebook correspondence, along with writing a detailed journal cataloging all of our sexual romps and encounters, and every single event, in chronological order, that happened the night of this 'incident', with names, times, and locations (as best as I could remember) - just in case she does decide to follow through with this.

I should be finished with the journal tonight, and I'm going to seal it in an envelope, along with all of the messages between us printed out, and then we're going to store it in his vault. I've cut off all contact with her, and I've distanced myself from anyone who even remotely knows her or her husband.

So, MR, is there anything else I should do to cover my ass?
