Why is it so hard to keep a handsome guy and trust him not to have an affair?

I’ve dated a lot of guys that in my opinion (my opinion) are handsome such as Hispanic and some Asian mixes. I discovered a lot of them are so hard to trust and get along with. They act arrogant and self absorbed and it’s hard for me to trust that they can be faithful since lots of other girls find them attractive too. Usually my relationship with them ends awfully. What are your opinions?
