Re: making a problem out of nothing 
You shouldn’t feel insecure, he is married to you and in men’s head, looking at girls doesn’t mean anything. It’s sad but in these things, men and women DO sometimes think differently. Dont stress about it too much. Just try to make a joke out of it, or if it really bothers you, talk to him about it but make it clear you’re not telling him off or accusing him or anything!
