So what!
Lol looking and staring is neither a crime or immoral. You need to.rethink your own confidence and insecurities. Just because another girl is better looking than you doesn't mean she has a shot with your bf
If it makes you feel better when most men cheat it's with lesser attractive women than their partner.
Your topic bores me but I hope it will equally bore you and you find some better things to direct your attention to like having an amazing time/experience with your bf because that's what sustains a relationship not good looks or people not staring.
