Why would I listen to you on this topic when your demographic has a worse track record on this matter? Within my community people lead happy lifelong marriages. Why should I listen to your "wisdom" instead of theirs?
You can call me misogynistic, I don't care, but then so are all the women in my community. If we take a worldwide survey I would bet my views are more common than yours.
People who sleep around a lot are less capable of long term love. I believe that and it is backed by research on the matter as well. If you care you can read about sociosexuality.
That there is a relationship between attractivness and promiscuity amongst women is something I disagree with. But it would not make a difference either way.
Most breakups from a serious relationship do end up with the people being jaded.
Emotions are definitely notinfinite. Quite the opposite.
BTW to not mislead anyone I am an atheist and grew up as a mainstream Catholic from Germany.
