I don't agree with cheating either, and I'm not suggesting anyone should.

I'm just saying it's hardly surprising when you force two people to get married that they may not love/respect/honor/obey one another. And many guys already have a girlfriend when they get married to another woman. How can you expect them to stop seeing their past lovers just because they are getting married?

If marriage isn't taken seriously by the parents (but instead seen as a transaction, or a convenient union of two families) then don't expect the children to take it seriously either.
