tl;dr: Is a good LTR worth giving up plates for?

Note: a lot of the purpose of this post is to resolve the cognitive dissonance in my brain, but also for advice when it comes to my situation with women. I'm covering a lot here as well, so anything is appreciated.

I've followed TRP for a while now. Here's my main concern with it: it seems TRP recommends plate spinning, PUA, withholding commitment, etc. while simultaneously pining for a more 1950s-America-esque traditional society where women get married early, have children, and are submissive to their husbands. This strikes me as odd, since spinning plates and having sex outside marriage would be very difficult, not to mention socially unacceptable, in such a traditional society. The 2 seem pretty mutually exclusive, yet I see support for both of them on TRP.

I guess here's what I'm really asking: I just got out of college and want to know how to live my life with regards to women. What's a better way to live my life: spinning plates, or living in a traditional society with a wife and kids?

When I look through TRP/the manosphere to find an answer to that question, I see commenters saying things along the lines of "well I wish we lived in a traditional society, then I'd get a wife and kids, but because of feminism, I have to spin plates, which is the next best thing". (These tend to be the men who bemoan sluts and the "cock carousel"). This doesn't make a lot of sense to me, as I am currently in an LTR with a very traditional, somewhat religious woman who cooks and cleans, is very sweet/submissive, hates feminism, and wants to get married and have children. I am confident that if I wanted to, I could move to the country with her, settle down, and raise a family with her; yet, on some level, I'm not completely comfortable with this arrangement, since I still desire sexual variety and am not sure I would ever be satisfied being with just her for the rest of my life. (A couple other reasons: to the average observer, she's probably a 7/10 on the looks scale, but I'd kinda like to bang a 10 at least once in my life. Also, I'd been in a couple LTRs before this one, and that feeling of getting into a new relationship and really hitting it off with/fucking a new girl feels really, REALLY good - it's the best part of the relationship, but it goes away and never comes back). I'd feel horrible leaving her though - she's basically the perfect RPW, though she doesn't know what RP is. Idk how easy it would be to find another like her, at least where I live (Seattle area).

Maybe I'm looking for that rare LTR who will stay faithful but let me have fun on the side, but I'd hardly find one of those in a traditional society. Obviously self-improvement, practice holding frame, PUA tactics, etc. would improve the chances of this (and I've been lifting and reading the sidebar religiously since finding TRP), but any woman who'd agree to that is probably not marriage/mother material.

Basically, I aspire to 2 mutually exclusive situations with women, both of which TRP seems to endorse. I will need to pick 1 or the other, and get my priorities straight. Any advice? All comments are appreciated.
