Is it worth breaking with boyfriend for ogling?

Ive been with my boyfriend for 1.5yrs. Whenever we go out together, I catch him olging at other women. Yes I do get upset when he looks at other girls. We've had numerous fights about it and its the ONLY thing we've ever had an arguement about. He doesnt do it everytime we go out, but if there is a hot chick walking down the street, he will look over. He hasnt cheated on me nor flirt with other girls, but Ive told him how olging at other women hurts me & makes me feel insecure, yet he still keeps doing it. He have a good relationship, only except, he ogles at other women, even when Im around. i dont know what goes on his mind when he looks at them. Even though this only ONE problem in the relationship, IS IT WORTH BREAKING UP THE BOYFRIEND OVER FOR IT??????
