Says who? I don't know what's so hard to understand about this. How many friends have you had over the years? Should your current friends be wary of the fact that your "friend count" is so high? Seems like your bond with them is pretty weak if you had the same exact bond with hundreds of people in the past, and they should steer clear of you.
It honestly just reads like misogyny, like women who have many partners are emotionally incapable of love. Let me tell you a secret, any semi-attractive & social woman will have easily had 20 partners by age 25-30.
Theres no such thing as the "same exact" pair bond 20 times. Each one is different. And if something is of a certain strength, then how can it be weaker because it happened before? The only way what you're saying is true is if the person was jaded by the previous relationships and can no longer form deep connections.
Emotions are infinite.
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.
Your only problem is that you are just as promiscuous so you stand on thin ice when you try to demand better from her.
