Help :(

So my hubby and I recently got married and I love him to death! He and I want to be with each other more than anything in the world! And neither of us can see a life without the other. But there's this guy at work that is really attractive and I kinda like him, and I feel really comfortable around him. I really wanna be friends with him but he also makes me have weird feeling about him... How can I simply stop this unhealthy feelings towards another guy, I would never cheat. And I do not want my marriage to fall apart because of some stupid mixed feelings toward another dude.
