There is a big difference between a casual double take at a pretty girl and an obvious stare or leer. A friend of my H's visited us while we were living in the Middle East and he was so ignorant the way he eyed the girls that my SON called him up on it. He tried to say there was nothing wrong with looking but he did it one time and told him the way he was looking a young girl up and down could end up him going to jail if she complained about him. If he did this while with his wife at home I would find it totaly unacceptable.

When I occasionally see my own H check someone out I tease him with a she was nice and we laugh.
If your H is chatting girls up at the same time as eyeing them up it will make you feel a bit insecure but doesn't mean he finds them more attractive than you.

If your H is working all the time and you have 2 young kids it is a tough period and very tiring for both of you. I know finance doesn't always allow it but even getting some help around the house one day a week can make life easier for you. Arrange a babysitter for one night at the weekend and this can help reconnect having some adult time. Its easy to forget you were a couple first once kids are in the picture.

Can see how easily resentments build up for both people. Him feeling rejected and you feeling he doesn't do anything to help.
Plus the looking on the internet is a big insecurity for you.
