I wonder if it's similar to the differences between introverts/extroverts. Some people love being partnered to the extent that the compromises don't feel like compromises and some of us can't see anything but the compromises and feel restricted.
I think the introvert v extrovert debate is often grossly over-simplified (particularly on here), so I don't think that's the right analogy but I completely agree with you that there are certain personality types which are better suited to the kinds of compromises required to make long term relationships work than others.
I think a fair amount of women in particular get a lot of their validation from making other people happy and comfortable (principally their partners and children) so for them the tedium and the restriction of a standard long term relationship is "unseen" because the greater goal is this sense of comfort and utility to others which is ultimately worth te sacrifice for them. Whether that's a personality type or social conditioning I don't know: I think it's probably a bit of both.
But a reasonable minority of people don't enjoy the feeling that they are principally accountable to just one adult person, and they should get most of their emotional/intellectual/sexual satisfaction from that person. They find it limiting and stifling. I'm definitely one such person. I've had a very small handful of relationships in my life which haven't made me feel bored, restricted and hemmed in.
The friction comes from the fact that all of us are heavily indoctrinated to believe that this one person for one person model is applicable to everyone and anyone who doesn't do well with that model is dysfunctional or selfish. It's very difficult to talk honestly about this without being accused of either being bitter or not having had the "right" relationship but I'm pretty sure that's an over-simplification.
It's certainly true that many women put up with shitty relationships purely to be in a relationship but I think there's more to it than this. A lot of women thrive on their own but we haven't yet developed the societal language to admit this.
