I recently got into a discussion with my boyfriend where I was discussing that cheating is so unfair to the other person and my boyfriend told that it is common and not a big deal.. This has been extremely shocking to me as my dad has cheated on my mom and I know how difficult it is for the other person who to come out of it. And cheating is a huge deal breaker for me.. I really love my boyfriend a lot but not able to react to this situation. Is this normal? Does everyone think cheating is not a big deal? Am I being too much of an idealist where I want to be with one person and love one person? I’m very confused, please help..
