Maybe you can call it survival instinct, that is how I view jealously. Our nature is to protect always our territorial integrity, no trespassing and women do it most excessively so it becomes annoying. Older and more experienced, I have managed to thrash 90% of whatever hormone is in charge of jealousy because a guy, with or without your approval will still go for that hottie. So why hit your head against the wall for nothing. My 2cents though. I hope you didn't get a bash from the jealous lady?..... .lols😂
