Fluffy,
you make getting a divorce an easy thing that is no big deal. If my husband wanted a second wife and I didn't, it would break my heart. Its hard to just divorce the man you have been married to and love- even worse if you have children.

So, should the wife get a divorce and become a single mom? Divorce is a very serious matter. And even if a contract is written up with no second wife stipulated, the husband can still get one if he wants because who is to stop him? The wife? Either she allows it, or lives unhappily with the thought that her husband wants to be with another woman, or gets a divorce and looses her husband?
