Throwaway for obvious reasons. I think I saw a similar post a while back but I can't find it or remember its title so forgive me if I'm asking something which has already been answered.

A while back, I met a girl who at the time I thought was perfect LTR material, she was funny and nice, very feminine to the point where she rarely wore pants or jeans, always skirts and dresses, she liked feminine activities like cooking and ballroom dancing, she didn't act slutty, no tattoos or piercings, very few male friends and their relationship wasn't lukewarm at best, all in all she was very girly and sweet but turned out to have a very masculine mindset later on.

She was frighteningly intelligent and perceptive, from the beginning of our relationship, I maintained a strong frame with abundance mentality and it seemed to work for the first week or so and then as if she knew exactly what I was thinking, she started fucking with me, she would suddenly change behaviors from very sweet to incredibly cruel in a short duration of time, for a while there I thought she had BPD and I started seriously thinking about ending things with her, she was scaring the fuck out of me, she would continue my lines for me, like when she says something teasing or slightly disrespectful, she would immediately say 'and this is the part where you say x' and it would be something very close to what I had in mind to say and she did that with everything, I maintained my frame and treated the whole thing as a humongous shit test but I will be honest with you fellas, I was freaked out like a black guy in a horror movie, I was sure I wouldn't survive it and I have no idea how I did it, she had a baby face and she would say these creepy things with a doll smile that wouldn't falter. I confronted her about her games and she said 'but you started it honey, is I too much? You can't handle it?' And I acted like I didn't care about what she does but that period of time with her defined mental exhaustion to me and it got to the point where I felt like one more word or action from her and I would shatter or explode, she was extremely sadistic and manipulative until one day out of the blue, she just decided to end it, said it was a 'fun ride' and gave me a peck on the cheek then cut off all contact with me. I was weirded out, relieved but weirded out because I kept imagining her comong back and it screwed up my head for a while then I got myself together after doubling the time I spent at the gym. Things went well but last week, I got a package delivered for my birthday and it had a sex doll in it (very realistic and expensive, she's filthy rich but that's besides the point) , the card said this was her do-society-a-favor monthly task by removing me from the dating market so she provided a sex doll that 'doesn't talk back and is always available' (echoing something I said before during one of her shit tests) and 2 cards for cleaning and cooking services which 'will cost less than the money I spend on women monthly'. I know she's messing with me, all methods of contact with her are still closed but I can't get rid of the feeling of paranoia now, I practically live at the gym and it hasn't helped, I feel mindfucked, how can I find a wayto slap me back to my senses?
