" If you love someone for real, you don’t want to lose that person. And if there is an opportunity of cheating, this feeling of love and possibility of losing should prevent the cheating."

The above is very correct. The love we have for our partner should be able to constrain us from doing things that hurt them. If I love you and can't sacrifice my selfish desires for you by being faithful to you, then I don't actually love you.

Thanks for your contribution. I appreciate.
