Input: You're probably already thinking "yes" because it's widely considered unreasonable to make that kind of ultimatum, but with context, I feel like my position will be a little more understandable.

I started dating a girl in April of this year. We were both sophomores in high school at the time and we were good friends for about 3 months prior to getting together. However, we had a sort of rocky history. Long story short, in 8th grade I was a real asshole to her. We mainly spoke online and that had the effect of both shortening my fuse and taking away my filter. She had some unresolved feelings about it even going into our relationship (2 years later), which I was fully prepared to deal with.

 However, it was impossible to see in advance the sheer emotional toll this relationship would take on me. Every day, multiple times a day, she would find something to have an anxiety attack about, whether it was "flashbacks" to 8th grade or something I said or did that day. 

For example, we once went out rollerskating. When it was time to go back to our friend's house, she wanted to take a picture of him using my phone. I didn't have a problem with this. However, when I looked at what she was doing after I gave it to her, I quickly noticed that she was searching through my dms on instagram. I have nothing to hide but I resented the fact that my privacy was being invaded, so instinctively I grabbed my phone out of her hands. She insisted she wasn't doing anything but I saw what I saw. 

She refused to speak to me on the car ride back to our friend's house. She refused to speak to me for hours going into that night no matter how much I pleaded with her to speak to me and explain what was going on, because at the time, I had no idea why she was upset. I suspected it was because of the phone but I wasn't sure. 

Later, while she was using our friend's VR headset, she knowingly made her way over to me and punched me twice in the face. She still wouldn't talk to me after this. After we were finished, we went down to the basement to watch a movie. I let her pick the movie. I discreetly texted my friend to go away for a minute so I could talk to her one on one and finally figure out what was going on. 

He leaves. I talk to her. She says nothing. I move over to sit on the same couch as her to get closer to her. She kicked me hard in the chest and then moved to the other couch. She still refuses to speak to me. We had approximately 30 minutes left until her mother was going to pick her up, and then we wouldn't be able to see each other for another week. (we could only hang out on weekends because I lived an hour away)

We eventually make up after I broke down into tears from pure frustration (in front of our other friend mind you, which I didn't want to do) and then she goes home. I go home as well and I text her, because we texted each other pretty much all day every day. 

She spontaneously suggests that we talk about our kinks. I tepidly agree because I know I'm walking on eggshells and I don't really want to provoke any more anger from her. She starts by saying that, because of how I treated her in 8th grade, she developed a sexual affinity for psychological abuse. She said she wanted someone to "tell her they wanted her to kill herself, then kiss her".  I, of course, told her I wasn't comfortable doing that for her but I don't judge her for having an uncommon kink. She then has a mental breakdown because I'm "judging" her and "I know you can't do that for me, my next boyfriend will." 

I spend hours into the night calming her down and reassuring her that she isn't being judged. This whole conflict is resolved at around 1:30 AM on a school night. This is an example of a more or less typical day with her. There were both worse and better days but it was generally around that level of awfulness.

On August 6th, I decide to break up with her. I couldn't handle being emotionally drained every single day anymore. For the first 3 months of our 4 month relationship (which is way too fucking short to be having these kinds of problems) I was essentially a doormat for her. After the 3rd month I became more coarse and abrasive and less tolerant of her breakdowns.

One example is we were doing playground mode in fortnite. She was killing me so I was killing her back. I was laughing and I thought it was all in good fun, since, y'know, it's a fucking video game, but she hangs up on me on skype and starts telling me that she "saw a side she hasn't seen since 8th grade", and that she was "scared". I told her that she was taking the game too seriously and that she was over dramatizing me laughing and having fun. This turned into a several hour long argument.

That's the type of toxicity that happened virtually every day for the fourth month of our relationship. There were multiple occasions where I was literally driven to tears just by being in her presence and knowing the constant pain she was in, purportedly because of me. 

So I broke up with her. A few weeks later, she attempts suicide. At first she says it wasn't because of me but soon after that she labeled me as the sole cause of the attempt. She had also threatened suicide to me during our relationship when she was on a vacation in Florida. She said she was on a balcony and she wanted to throw herself off, "solely because of me." 

To get to the point, I was perfectly fine with our mutual friend, who I will call N, maintaining his relationship with my ex. If demonizing me was how she coped, then fine. As long as she wasn't proactive about trying to ruin my reputation or get me into genuine trouble, then I wouldn't have any problems with it. 

Recently, my dad bought a house in my ex's town and we're moving there after Christmas break. This has absolutely nothing to do with my ex. Most of my friends live in that town because I attended school from 3rd-9th grade there. I told N to notify her because I wanted to give her time to cope before seeing my face in the hallways, since I knew that would be painful for her. 

She immediately goes into a downward spiral. She's frantically posting on social media and actively trying to convince popular and influential kids at our school that I verbally abused her. She threatens to post screenshots of the alleged abuse. N saw the screenshots and said they would help my case, not hers. 

Now I'm not popular, but I'm relatively well known and people just by knowing me can tell I would never abuse someone the way she claims I abused her. 

Here's the part where my dilemma comes in. After realizing that she won't have any luck convincing people I abused her verbally, she tells her parents that I abused her physically. She claims that I left bruises on her and that she has a friend who saw the bruises. Her parents contact my father and threaten us with the prospect of filing a police report.

I was perfectly comfortable allowing N and my ex to be friends before any of this happened, but the fact that she escalated it so much in such a short time (less than a week from when she found out I'm moving back) I decided I no longer wanted to share mutual friends with her. N and I have been best friends since the 6th grade. My ex and N have been friends for less than a year. 

I told him that, under normal circumstances, I'd have no issue with them continuing to be friends, but in light of the fact that she made an earnest attempt to sabotage my future out of spite, I was no longer comfortable with them being friends. 

He told me that it wasn't my place to determine who he's friends with. I agree, but I think it says a lot about his character that he wouldn't just stop being friends with her on principle. She did, after all, threaten me and my family with legal action based on a lie. 

A pretty heated argument ensued. I told him he didn't understand that not only had I not abused her, but she abused me, both physically and emotionally. He told me essentially that it was my fault for not leaving the relationship sooner, that "there was no gun to my head".  I told him to steer clear from me and blocked him on everything. 

&amp;#x200B;

**TLDR:** I have an ex who used to have manageable levels of craziness, but now that she learned I'm moving back into her town, she threatened to take me to court for physically abusing her (which never happened) and my best friend, despite this, refuses to cut her off.

So, AITA for not wanting my best friend to remain friends with my psychotic ex?
