SGB- what actually makes you happy? You do sound very jealous. Maybe if you went away and did a doctorate or something on this it would get it out of your system once and for all, and you wouldn't need to spout the same old lines all the time.
I have crossed swords with Mal on several occasions but I'd like to applaud her post as it echoes mine ( which I see you chose to ignore!)
You do come across as increasingly bitter, and it does smack of "Well, it didn't work for me, threfore it's not right for anyone else." You behave in precisely the same way as you accuse others of behaving. Can you not see that?
I don't know how you can't see it, but your remarks and generalisations are offensive, and patronising to the vast numbers of men and women who want a 1:1 relationship- yes, it might be serial monogamy- and who also have brains and judgement. You insult people who want monogamy by saying they are brainwashed into it. Women who have degrees, doctorates, highly professional jobs- are they really so gullible? Come off it.
As I said previously, if you care to read any anthropological or sociological articles that are not written by prejudiced feminists you would find that monogamy is millions of years old and is the best way to protect the species.
One of the reasons it may not work so well now is that we live longer- it's not that long ago that we all died at 40, and people change over 50 years so that's why serial monogamy is now almost a norm.
YOU might not want one person ( and yes, we all know that one person cannot offer everything we want) but maybe you can stop trying to convince us all that it's some kind of wicked plot devised by men and the media to make women "servants" to men's needs.
You do your own sex a huge injustice with this kind of patronising rubbish.
If you want to lead a life of swinging and just having casual relationships, that;s your choice. it sounds shallow, sad and a nightmare to me, but I wouldn't be so insulting as to say you were brainless when choosing it.
Going back to the OP- I think you should do what you want, but your DH has got to be in full agreement and once you go down that road there is no turning back. Some would say that you don't love him enough if you can tolerate the idea of him having sex with other women, others might say it's a case of having your cake and eating it, but if that's what you both agree to- and you are open with anyone else who gets drawn into it, that's fine. Yourlife!
