What would be God's opinion in this situation?

obviously you dont know what your talking about if you want to divorce your wife because she had before you were married. the way you say it it sounds like she was cheating on you when you were still dating, but if not you have no good reason to be mad at her other than that she lied to you, and that is a pretty pathetic thing to divorce someone over. If she lied to you about being a virgin then the chances are impossibly small that she did it to hurt you. more likely than not she wanted to be with you and feared that you would leave her if you knew she wasnt a virgin
