Hmmm... This whole time you only mention that he talks to other girl, never once did you said he cheated on you. So if he never cheated on you then, I don't see what's really wrong. He just want to have a little fun and see if he's still got it. If he never cheated on you, then to tell you the truth, guys like your husband are just flirt. Meaning they are actually really 100% faithful to their wife or g/f and would never cheat on them. And maybe he act like he don't care if you do the same thing because he don't want to look weak, too caring or jealous. But in reality, he really does. So I don't think you would have to worry about him cheating on you. But if you don't like the way how he is talking to girls, then talking to him is not going to work. To tell you the truth I think it's just going to encourage him to do it more. Because he know it gets you jealous, and going to keep doing it, just to get your attention and more jealous. For guys like your husband he's not doing it on purpose to hurt you, but actually to get your attention and see, if he can still get you jealous.
