how do I get rid of a kink :(

my ex got me into petplay a few years ago. when they first introduced me to it (through a fic they liked and shared with me), I didn't get the appeal and we moved on. towards the end of the relationship I started really getting into it for some reason, I think I kept looking at certain media out of curiosity and one day it just hit me like a train. by the time I fully realized this, we had went our separate ways and I got into my current relationship of 4 years. I love my girlfriend endlessly and we want to build a future together. I'm definitely kinkier than she is, and she'll indulge me with some of my (milder) kinks, but our relationship isn't very sex-forward at the moment and I'm okay with that.

problem is! she got a dog a while back, and somehow something in me gets torn up watching her interact with it sometimes. I haven't even met this dog yet, we're temporarily long distance, but it's eating me up inside and I don't know what to do. I know this is definitely some sort of trauma response from childhood neglect/cptsd (and I'm working on it in therapy) but to see her constantly praise the dog, have her life revolve around it, cater to its every need, teach it obedience... something very irrational and ugly bubbles up in me. I have never been loved so wholly like that and it kind of makes me really sad. i have never had that level of emotional attunement, never had my needs met so easily, never have been loved so deeply that I am someone's "whole world." on top of that all the "good girl"s directed at the dog makes my chest heat up in an awful shameful way. I know my gf isn't into the whole petplay thing but she does call me a good girl at times and while I do like it a lot, the fact that she says it all the time to her dog does something to me and I wish I could make the feeling go away. I know she truly loves me, my mind has just been torturing me.

it is extra tough right now because I have been really isolated and don't really have any family to turn to for emotional support. most of my friends are long distance and don't have much time for me. watching my gf revolve her life around this dog really hurts for some reason. the feeling has honestly spread to other dogs too, I will see someone walking their dog and get SO activated, I just want someone to care about me the way they care about their dogs. it's so hard to see a needy, loud, messy animal get such unconditional love and devotion, when all my life I have tried to quietly shrink into myself in hopes that would finally make me easier to love. I wish I never learned about this kink because I don't think I'd feel this intensely without it. I've toyed with the idea of opening the relationship while we're long distance in hopes that I could get the kink fucked out of me (maybe if I indulged in it, it wouldn't be as heavy on my mind?) but I honestly don't want to be with anyone other than my gf and I think this exploration would only make the kink stronger. I just want to stop feeling like this!!! I've talked to my gf about the way I feel, minus the kink stuff, and she's been respectful of not constantly flaunting the dog in my face but I don't know how I'm going to keep going like this. it lives in my mind rent free. to make it worse I literally have to interact with dogs for work sometimes and it just makes things so much harder. I just don't want this kink anymore and it's honestly ruining my life with the constant rumination cycles. any advice on how to condition myself out of it? tysm in advance :*
