Basically as per the title.
My MIL is an individual who is well known to take things way too far with everyone. Last time I was visiting her it was because she wanted BF (her son) and me to move from our city apartment into her sleepout in the middle of nowhere.
I've always been able to feel immense jealousy and resentment radiating from MIL and always privately felt like she was going to try and harm me one day.
Well, on this trip I was finally proved right.
I was drinking with MIL, MiL's crackhead best friend at the time (they are no longer friends because crackhead drugged MIL twice, but that's a whole other story for another day) and MIL's other son.
Everything was mostly okay. We discussed mostly normal things, had some laughs, discussed crackhead's dog who had had to be euthanized recently because it attacked someone, I expressed my sympathies. Everything was mostly alright.
At this point is where I fucked up. I talked briefly about how I'd been frustrated recently with my struggles with my mental health and about how I felt crazy because the medications and therapy I had been trying weren't very effective. I know it was dumb. I know I should never have brought it up and shown weakness. All I can say is that I was heavily medicated at the time and I had had a few drinks, but looking back I recognize I should have never thought for a second that I was among friends.
Annnnnd cue the bullying from MIL and crackhead. The usual boomer type of bullying you'd expect, telling me nothing I've done in life is good enough, I need to try harder, I need to do more, I need to be more social, I need to open up more, I'm the problem in my own life, nothing I had achieved meant shit etc etc etc. I excused myself to go and see BF in the sleepout and take a break because I was getting upset.
I then decided to go back into the house because I needed the restroom, and I remember thinking maybe I really am the problem. I thought about this for a bit, and then it occurred to me that they were all probably in there talking shit about me as soon as my back was turned.
Sure enough, I walked back in and the smiles dropped off all their faces as soon as they saw me because they had indeed all been talking shit about me just like I thought.
I went to the restroom and when I came back out, I said into the awkward silence "by all means, keep talking shit about me, don't let me stop you"
Now, I was quite drunk at this point so I don't remember exactly everything that was said after that. But I do remember that I should once again have just kept my mouth shut because this is where the entire night truly went to hell.
I asked why she wanted me to come here, let alone move in when she clearly doesn't even like me and I said that her wanting me here at all must have been a lie.
Next thing I knew, MIL was in my face, repeatedly physically pushing me around the kitchen, trying to provoke me into a fight. I wasn't taking the bait because I'm never a violent person no matter how inebriated I am, which I'm sure just made her angrier because she kept pushing me. Her son who was in the room had to come and pull her away from me while crackhead just sat there enjoying the show.
I went to the sleepout to inform BF about the situation. MIL then burst in and started repeatedly throwing beer on me. I was tired of being assaulted at this point so I told her I would call the police, to which she responded "if you call the police, you're fucking dead" and stormed out, screaming to everyone else about how she wanted me out of her house immediately.
She came back in a little bit later and started on a very long and very insane rant about how hard it is being a mother, how my BF had apparently broken her heart as a teenager with his depression and how at the time he had wanted to use his phone/the Internet to talk to his friends (which was wild because during that time period in BF's life they were living with her physically violent schizophrenic partner and she hadn't even given BF a bed to sleep in, only a broken old air mattress that would deflate completely overnight so obviously he was depressed and wanting to escape reality) how I'm full of shit about my PTSD diagnosis, every professional that has ever diagnosed me with PTSD is full of shit too, that there's absolutely nothing mentally wrong with me and I'm just making it all up, how it's my job to make her son happy and if I'm not doing that I have no use. I don't remember the rest of it because I was highly triggered and eventually began to dissociate. Eventually she left the sleepout and me and BF discussed going home as soon as possible.
The next day I of course had to go and apologize to her, because why wouldn't I. She was apparently deeply offended that I had accused her of lying and that had justified all her actions. Whatever. I smoothed things over even though I shouldn't have had to.
Me and BF were able to get home without incident. He has been back since, I have not. You are probably going to say "why didn't BF put a stop to it?!" because I can absolutely assure you from past experiences, he couldn't have. Once that woman gets going, there is no stopping her. Things would have only continued escalating. He did back me up and take my side, and we were able to work together to get home safely. He understands why I won't be going back. All is fine on that front. It's actually worked very much in my favor that MIL took things so far right in front of his eyeballs, because now I will never feel any pressure from him to play happy families with MIL again.
Anyway. Fast forward to present day.
Several months ago, MIL sent me a text message apologizing for this incident and her behavior. She lamented that I'll probably never visit again but that she understood why. I messaged back thanking her for apologizing and that there are no promises but I'll think about it (I said this mostly just to keep the peace because I don't want any more drama, not necessarily out of sincerity).
Now BF is currently down visiting her and she wants me to go there too and she'll pay for it. I have told her I'll think about it. I don't want to go. She'll be seeing me when she drops BF home anyway so I don't know why I need to go there. She is very good at making people feel like they're in the wrong, not her, and consequently I still doubt myself.
I truly just don't understand why she supposedly wants me there. I don't understand why I have to be put in a position to say no. I don't know how to say no without causing another big drama. I feel like if I say no I'll be the bad guy somehow for "holding onto the past" or "not forgiving and forgetting" or "holding grudges" or some other such nonsense. I actually don't hold any malice, I just simply don't want to ever be in any situation that makes me feel physically or emotionally unsafe.
Any advice on how to say no without this blowing up in my face would be greatly appreciated.
