Husband Secretly Flirting?

He could be attracted to her, yes, doesn't mean he's gonna try anything. I know I've flirted with other women while in a relationship just for fun. His keeping it a secret though is a little concerning. Ask if this girl knows he's married. And tell him that its starting to bother you because like most men, our happiness is greatly influenced by our girls' happiness. If something he's doing makes you uncomfortable he'd likely stop doing it. Or at least be willing to discuss it.

Yes. He is building a bond with her. I would seriously talk to him. If he is talking to her on the phone and texting and taking pictures? He wants it to go somewhere. A married man doesn't act this way. Sorry, but if you don't stop it, the bond will grow into more. That is why he hid it. Because there are more feelings this time.

You should really speak to him about this and how you feel about that girl! Something might be going on with him and he might not want to tell you, so talk to him! But I don't think he's attracted to that girl, they might friends!
