What does it mean when a guy can’t help but look at other females when he’s in a relationship?

He came home today and said this girl at the shop was getting really nervous around him and she lost control of her thinking. Dunno why I need to know that but yeah I know a lot of girls look at him but he can’t help but look at like every single girl to see what she looks like like there’s this girl at the motel where we’re staying at and he keep looking up at her door to see if she’d come out again, I think it’s awfully rude to think I don’t notice this!

I’m thinking of breaking up cause it’s making me feel insecure and jealous, it’s not a good look. 👀 or to feel this way constantly
