It depends. It says in Bible, if one is cheating you can. I can find scripture on marriage tomorrow if youd like. Just comment and ill get back to you. This way you'll know scripture. I was just going to bed. Wife put lights out, so i cannot look. Thank you.
In order to judge about its being right/wrong, one should first investigate into what lead to it, and what the consequences will be, although it may be legally permissible. For instance, after the divorce, the children will deprived of a parent.
First off marriage is a commitment. And it should not be torn apart unless someone is committing adultery. In the bible it says that if one turns away from god then the nonbeliever has to want the divorce in order to make it ok. I don't know why that is but that's what it says. Not exactly sure where but I remember reading that in the bible
