He obviously does not want to be emotionally involved with you. It may be that he focuses too much on the physical aspect of a relationship. Certainly what you want is not unreasonable. If he loves you, it's only common courtesy to treat you with respect - staring at women in your presence is not respectful. I'm sure there are many times when he can look when you're not around.
Men do tend to enjoy looking, since they are easily aroused by visual images.
That's why porno is so popular. However, there is a limit to how much looking is okay without becoming a temptation to commit adultery. You might insist on couple counseling if you really want to try to save the relationship. Otherwise, decide whether or not you can accept his behavior and find other ways to find personal contentment. You could make your own friends, take up hobbies, get involved with volunteer work - all these activities would bring you in contact with others where you could get some emotional satisfaction.
