My answer was (1), but CR is only one of several venues for me. Most of the women I see are courtesans that I have known for a few years, and I have been following this lifestyle for just over three years.
The best part is that I have met some seriously interesting women. In the social programming we get, I would have to decide on an SO - one SO - and then we would have to struggle through the "relationship." I am far happier with several ATFs, and it costs about the same. And damn but I have more fun, and can count several amazing women as friends - friends where there is a constancy to the friendship. It's not the intensity or dedication of a SO thing, but there are several that I would see in the hospital, and otherwise do SO-type things for. (None in CR so far.)
I just think that civilization has reached a new threshold as far as the character of interpersonal relationships, and that the social systems have not caught up and are holding most of us back.
Or maybe I am just a hedonist. There is no way I could enjoy the full variety of life as I see it with just one woman, and I don't know what's in store for my next time around. For this punch of the card, I am going to have the experiences I want to, rather than living in quiet desperation.
Of course I don't know how this will all play out for me in 20 years, but I do know how it does for the societal norms. (And yes, my parents are still living, together, and caring for each other.) At some point I may find that I am fooling myself.
But there are enduring elements to several of these relationships, including with some ladies that are no longer or never have been sexual partners. And as I said, truthfully, I would be there if they were in the hospital, and I think it would mean something to be there. Some are within 10 years of my age, so we are at least on the same general side of the age curve, and are thinking about the final end game.
And of course there is the 20-something tica that says she is in love with me.

I can see me as a 70-something, on a modest plantation, helping her raise... well, more like worry about her K*ds at that age. Who knows.
One thing for sure, I have enjoyed taking the path less traveled by, even if the end may not promise all that my parents have. There are thousands of species of birds, but only one of humanity. My belief is that Providence has put us here to explore the differences, not to reinforce the norm. I would hope that we can discover and expand what being alive offers.
I would prefer to lament not having what is known, than lament what I did not try.
