There’s a possibility that a person can get attracted to another. It’s human nature. It’s not wrong. But that is why you’re in a commitment. You discipline yourself. One may get attracted to numerous prospects and it’s okay. As long as you don’t nurse the feeling and do something about it. Borderline between cheating and faithfulness. Recognize reality that you already have the person that can give you more than what you get from the cheap thrill of attraction.
