They can repeat that lie a million times but it still won't be true.
I went through most of the long article. Seems like the author was on the defense the whole time and the conclusion...THEY ALL FEEL JEALOUSY, then they use cognitive therapy to come to a self-accepted-truth (not an absolute truth) and believe that to calm themselves.
Evolutionists always miss the mark. The Creator made us in His image. We really all want to live with one person for our whole lives and die together unless Satan has perverted us.
Sure it is true. When you view a lover with the same emotional attachment and commitment as a blow up doll, a vibrator or a towel, what is there to get jealous about? If he/she/it leaves then you can always find a new receptacle.

If you Google a bit you can find pictures of these freaks. I think in this limited case, lack of jealousy is a distinct possibility.
