I don't know how else to try to explain it to these two, so this will be my last attempt.
Monogamy is NOT natural. Neither is getting up and going to work every day. Neither is eating a piece of fruit when you could have chocolate cake. Neither is not ramming into some car that cuts you off on the interstate.
We control our impulses every day, as part of maintaining an ordered and structured society.
It is not unreasonable to ask a woman to control some part of her impulses, nor are there women who won't do it. And like I said, it's more so (to me at least) for the health and pregnancy protections than anything else. Monogamy may not be natural, but it's practical in some circumstances, especially in limited durations.
The reason cordon says you're insecure is that it's obvious that deep down, you are too ashamed of yourself to actually believe that a woman would care about you so much and value you so highly, that she wouldn't go fuk other men. Your "game" is indifference, which works wonders on psychologically damaged women, but doesn't get you very far long-term with a quality woman. They want commitment the same way a man wants sex. You feel yourself unable to attract, or keep a woman on the basis of anything other than sheer apathy. Apathy doesn't build relationships; it just makes a woman willing to fuk you a little longer. Eventually, any woman that is worth a sh!t will leave you unless you can demonstrate substance - which for you, apparently, is too much to ask.
I have also found that people who hate the thought of having children, secretly just hate themselves. I love myself; it's why I want to have children to teach and continue my bloodline.
Personally, I'd suggest therapy, and a healthy dose of self-esteem.
If you can restrain your OWN natural instincts and create value in society, then she can do the same. If she's a Cluster B or drug addict, maybe she can't do it. But there are normal women out there who you will have no problems with, if you are giving her what she needs.
Good luck.
