Why do I keep looking at other guys?

I have a boyfriend but he's in a different country I really really love him but every time I go to the mall I see really cute guys that r cuter than my boyfriend so if I love a guy and I think other guys r cute does it mean I don't love my boyfriend or wat? Even though I look at other guys I feel like my boyfriend is the one for me and that I should stop looking at other guys I really love my boyfriend so how do I stop looking at other guys? And do I love my boyfriend?
