If you are in a relationship, and his eye is wandering, you catch him checking out other girls when the two of you are out, there is only so much you can do. Even in a marriage you can’t stop someone from looking, so how can you expect it in a younger relationship? You are still a teen, and so you should not be getting too serious yet, but that does not mean you want his eye wandering. So, what can you do to stop his wandering eye?
• You can ask him about it. Sometimes guys look because that is what they do. You look too, you are just better at it than he is because you know how to be discreet. He may not be looking because he is dissatisfied with you, but because he is a young guy. You have to realize you are still young, and so is he. You are around hundreds of people of the opposite gender each day. So, how can you really expect him not to look some? He is looking to figure what it is that he wants, not because he is looking for someone better or new. However, simply mentioning his wandering eye and the fact that you notice it will help him to control it more.
• You can change something about yourself to try and grab his attention again. Sometimes things get a little stale. You are young, there are tons of new girls to look at each day, and if you have been dating a while, he may just want to look at his options a little. You probably do it too! So, change your hair cut, color, or style. Buy some new clothes, and get ready every day so that he never has a reason to look somewhere else. If you do not want his eye to wander, you better ensure he has a pleasing sight to look at in you.
These are really your only two options. The truth is, as mentioned above, stopping it is really not entirely possible, but limiting it is. You want to be the center of his life, but chances are he is not in a place in his life yet where he is ready to make that HUGE of a commitment, and you shouldn’t be either. You are young. He is surrounded by females, and expecting him not to look at them is silly. If more than his eyes wander, then it is time to really put on the stops. If his hands wander, or his lips wander, then you need to break up with him. However, if it is just his eyes, you should be grateful he is normal, has hormones, and is attracted to girls.
So, do not try to stop him from looking. Be glad that he is looking, and be glad that even when he is looking at other girls, he is coming back to you. What should that tell you? That means that he wants you. He knows his options, and he is choosing you still. So, instead of being less secure because he is looking around, you should be more secure.
Now, if he is checking out other girls when you are out on a date, or when he should be paying attention to you, then it is a problem. Then, you need to put your foot down. Then you need to call him out, ask for a change, or break it off.
