Western culture has tried to divorce monogamy from its rather distasteful roots for roughly a century now, and the results are... well, not promising.
Maybe it's not promising because people are a mess, and always have been. Just a thought.
I'm all for not throwing out the baby with the bathwater, but the whole idea of a kind of ownership-relationship hinges upon the very demons they tried to exorcise to begin with. When even desire for another person assumes the guise of betrayal because of the way relationships are conceived, and people cannot form even closer bonds to others because they are "taken" (like a seat or a car), things are heading in a *very* unhealthy direction.
I can understand your sense of irritation with this whole thing, but I also think that at least some of the way we each conceptualize the inherent meaning of "relating" to other people is mediated by the ways in which our felt needs grew during our respective social situations when being raised.
Personally, I've never conceptualized my marriage to my wife as being somehow a form of "ownership." My wife is mine, and I am hers, but only in the sense that this means that I expect others to respect my relationship with my wife and not try to horn in on it. Inversely, my wife should be able to assume (and expect) that I won't go seeking companionship of a more intimate sort with any other women. And I think she has the "right" to expect this of me.
Serial monogamy is just as miserable, especially when under the umbrella of an ideal that promises One True Love: because it means that for the new relationship to start, the old one has to be irrevocably cut off and denied as a "wrong" choice. There are plenty of people who celebrate their third or fourth marriage, each time believing that THIS time, they've got it "right". Poor sods.
Yes. Poor Sods.
............whether or not serial monogamy is 'bearable' may depend upon the presence of various socially forming factors in the mind and life of any one individual. To simply say that serial monogamy is miserable seems to only indicate that it may be so for the person so saying that it is .....
On the other hand, I do not believe that there is a one-size-fits-all relationship model. *Some* people are perfectly happy without any romantic or sexual contacts in their life. *Some* people fall in love once and stay together for the rest of their lives. *Some* grow apart every couple of years, starting new relationships and abandoning old ones. And *some* take totally different routes.
On this particular nuance within the makeup of relational human choices, I think you already know where I stand on this kind of psycho-social subject, that is, if you've read anything from my recent forays into the topics of Raunch Culture and Hugh Hefner's philosophy.
On the one hand, I can definitely say, "Down with Patriarchy!" But on the other, I don't seem to be irritated by the same intuitions that may accompany the act of saying, "Down with Monogomy!" Sure, there's many an attractive woman (and man) in this world, but just recognizing this fact is a very far cry from thinking I've just opened the door to Baskin-Robbins.
All of that can be valid, provided that it does not involve violations of trust, boundaries, consent, or agreed-upon rules. And I'd very much prefer it if people consciously and deliberately choose a relationship model than try to live up to one that makes them (and thus every other person involved) miserable.
I tend to think that the validity of all of this will go quite a bit deeper into the rabbit hole than all of that.
