While Iranian men can divorce almost at will...
Islam is evil.
Ummmm....You saw this part didnt you?
Under Iran's Islamic laws, a man is allowed to keep four wives at one time, a right not granted to women.
Even if a husband is having an affair, he can claim to have undertaken a "sigheh," or temporary marriage. It's a contract allowed under Iranian law that allows a man and woman to be "married" for any length of time they choose.
