Would a guy leave his girl for a prettier girl?

Anonymous
I have seen cases where a girl was incredibly jealous when his boyfriend was extremely good-looking even if he takes a glance at another girl. I know some girls who deliberately get together with not so attractive guys for this reason. I have known one girl who lost her boyfriend to another girl I’m assuming she was different somewhat? Do u agree? If the guy is good-looking and the girl is alright looking?
