Reading through this forum, as a woman (18yo) on raw primal, wanna say that @Jack knows what he’s talking bout. I also have some input and advice, as a girl who has been open minded and experienced radical change, all for health.
Stop all the doomer shit about it being impossible. I know it feels impossible, especially when you’re reminded everyday about how brainwashed and close minded everyone around you is. When you feel like an outlier, and cannot reach and teach your family and friends, of course you’re gonna feel hopeless and lonely, but please don’t let those feelings of isolation and difference convince you that there isn’t anyone for you. I am living proof that raw primal girls/woman exist, and, despite being convinced I was the only one in my country, I have found several others. It’s not completely rare, people are awakening 
I firstly suggest, to find a raw primal woman, you have to be open minded, as you’d want her to be. If you’re insanely close minded and dogmatic about this lifestyle, as well as fearful that you’ll never find the one, you’re not gonna get anywhere, you’ll only attract what you don’t want.
I’ve also noticed that a lot of raw primal dudes have fucked up views and standards about women, like Epstein level, “I’ve gotta find a super young, perfect stacy, virgin wife, who will completely align with my beliefs and do whatever I say, and let me own her and make her my baby machine,” typa shit. That’s very unrealistic and truly corrupt, women are humans who deserve their own agency, opinions and values, that are just as important as your own.
(if you ever do find a girl who subscribes to that role, you’ll quickly find she either has absolutely no sense of self and personality, or rather, she’s a mossad agent. Up to you if you can live with that
)
So if that even slightly reflects your true desires, I’d suggest you evaluate where that comes from within you. And, before you say, “but it’s naytrull” or some goatis bs, evidence suggests that, in our hunter gatherer era, societal structure was matriarchal and relationships were non-monogamous. Non-monogamous through woman having babies with multiple men, as, if you think about it, that would optimise the survival of her children, so they could all be protected and fathered by many.
I do not believe in the same relationship style today. Humans aren’t just baby making flesh vessels who need to survive, but rather souls who unite, to love, as both perfect matches and opposites. Religious, spiritual, or not, relationships are unarguably, a bridge to the divine, an experience of life that transcends the mundane.
To find your match, I believe you need to focus on being an independent and whole unit, aka self actualising and Individualising to an extent. When you rely on finding another to make you feel whole, you’re gonna keep going thru samsara buddy. Stop searching, find the love within you and within your life, then love will naturally find you. Same goes with authenticity and finding the right person for you, you gotta be it before you find it.
Yeah this became a lot deeper than expected, but It just feels right to express and say this all. I am speaking from a place that has seen how the raw primal and incel community can, in some instances, become one in the same. Take what resonates and leave what doesn’t, but don’t let yourself become another pessimistic woman hating chud just because you feel lost and lonely.
Some last things I wanna say, is that your habits have the ability to inspire another, don’t think that just because your girlfriend/romantic interests diet is unhealthy or unaligned with yours, that nothing can be done. My ex boyfriend took me from hating ruminant meat one day, to eating a steak everyday following. Just from him encouraging me to try it, without any pressure or expectation.
So don’t approach it from the “I’m gonna change or convince her”, rather, be the blueprint and let your habits and visible health benefits lead the way first. While also taking small actions, like encouraging her try raw meat or sashimi, or even blue rare steak (bonus points if this is at a fancy dinner you paid for).
I also wanna suggest looking into Duru Bilimlier, she’s introduced many woman to the diet through her social media and community. Framing it as a way to look gorgeous and slim, and experience healing from all sorts of health issues that women suffer from. There are many other influencers who are woman or work with woman, all this kind of content could be shared with your girlfriend, especially if she struggles with the mentioned health issues. Be careful tho as a lot of it is framed as a way to lose weight and increase beauty, you don’t want to suggest you think she needs that.
Hope this spiel is of some value. It’s definitely very valid to want a relationship with another healthy person, that’s for sure a standard of my own, just don’t let it get you too dogmatic and strict. Ultimately, relationships are about love and connection, the addition of beauty and enjoyment to your life, rather than the only source of it. So focus on being healthy, happy and enjoying your life, and you will find someone to join you in that 🫶
