For the first 2 -
Divorce is a sin no matter how you cut it. Even if your spouse commits adultery, divorce is a sin.
This sums it up nicely -
Quote
Man broke the contract he made in his heart, to be with his or her spouse till death.
What Moses did, by the will of God, was permit a certificate of divorce to people who were already divorced in their hearts. Because they had hard hearts, this is the only thing they would understand. They were already divorced, by their own doing, and their own sin. They broke the covenant of marriage already, just in seeking to be unmarried.
They simply couldn't understand it unless it was "legal" and on paper. Moses permitted a certificate of divorce, not because God "allowed" it... but because they were already divorced. They were already divorced, in their hearts, and the documentation simply provided them with the only thing their hard hearts could understand. Black ink on white paper.
As far as the adulteress part (question 2), marriage is meant to be a lifelong commitment to your spouse. This includes the sexual relationship. When you divorce and have sex again (other than your original spouse) you're committing adultery since the sex you are having is not with your first spouse. Even if you remarry it is adultery because again, you are sinning against your first marriage. There is a lot of debate of whether it is an ongoing sin, or just 1 act of sin. Meaning, every time you have sex with your "new" spouse you are committing adultery against your past marriage. I tend to believe that it is a one time sin from the time you first have sex with your new spouse.
The other 2 responses answered question number 3 pretty well.
