Love issues

So a problem we are having in my relationship is we are both having major self confidence issues. My boyfriend has always been like this. He has never been ok with me thinking other guys are even the slightest bit goodlooking. Maybe at the beginning it was better. But it is so much worse now. He gets upset when I call a guy "ok" and "not ugly". the only guys other than him that he thinks I think are not ugly, are Johnny depp and Gregory peck. So this has always been crazy and annoying and it has gotten me to just go along with it and never say Gus are goodlooking, when he would totally have the right to call a girl pretty. It would hurt me but I would get over it. I guess I'm just stronger than him. But this unfairness always bothered me. But now it has completly rubbed off on me and it breaks my heart when he calls a girl pretty. We are both like this and it has to stop. How are you and your boyfriends when it comes to talking about goodlooking people? We both promise eachothwr that I think he is the best guy j the world and he thinks I'm the prettiest girl in the world. I feel like ts sooo unhealthy
