I know this sounds like an easy answer but it's not.
I was having this discussion with a friend today.
Supposing a Christian man and woman falls in love and gets married vowing to love each other till death.
They have a healthy, explosive sex life but somewhere along the line the man left her for another woman.
He flies for divorce goes on to marry the new woman
The woman remains single and shares custody of the kids woth the husband.
But they continue to have sex ocassionally.
It may be immoral but is it sinful especially since the Bible [b]for the most part is against divorce ?[/b]
And the woman in this case never stopped loving the husband despite what he did to her and would like him back.
