Some really great thinking here on such a complicated subject. I think how old you are has to do with what you prefer as well. I think that as you get older the monogamous relationship becomes more attractive. And then when you throw kids into the mix, well, it seems like you can't really take the risk that someone might want to go off with another person for good (which can happen) because you've already made a commitment to your children. Frank and Claire didn't have any children.
That makes sense. I didn't even consider children when I wrote this. Honestly, I thought you were going to tell me that polyamory becomes more attractive for older people because they've gotten tired of having the same partner for so long!
ha! That's a good point. I guess in the end it's just different strokes for different folks. As long as we are all at least somewhat open minded with each other and allow each to do their own thing, I suppose it all works out. That freedom doesn't exist everywhere!
