what u do about ur man checking out other women?

i hate my husband, i hate how everytime theres a young woman in public or online like youtube or tv, hed stop what hes doing, and check her out. he clearly doesnt have eyes for me only =/ he does it to everyone of them, especially asian women. yea, he prob thinks theyre cute or attractive, but it just bothers me. am i just overreacting to his behavior? or somethings not right w him?
