Healing her mind...
All sin starts in the mind. Have her walk you through one of these sinful thoughts from the very start of it- what brought on the thought, how she felt emotionally and physically, even what time of the month it was. Really break it down into tiny bits, and discuss one bit at a time. Analyze where her thoughts started to go wrong, and replace that thought with scripture and logic. Show her that she's allowing the desires of her flesh to speak louder than her conscience, and that this happens by allowing the desires of her flesh to come so quickly that it tramples over her conscience before its allowed to speak loudly against it.
What she has to do is identify quickly that this is the start of the thoughts that lead me to sin. Once she recognizes the start, have her imagine putting it on a shelf in a box (quickly), and have her imagine that next to that box on the shelf is a picture frame. Inside the picture frame is a picture of you with tears in your eyes. Have her feel the hurt you would have if she would take the box back off the shelf. Give her a sentence, just one sentence, and request that she says this sentence to herself when she is tempted to go against her conscience and against you. We are all tempted, but God will provide a way out. If temptation is the only one there to speak he will win.
YOU- you have to be there, in her mind, to speak to her heart and say, "Consider your love for me, consider my tears and my broken heart. Here I hold out my hand, take it and place it on your heart. Come to me. If I'm not here call my cell and say, "I just needed to hear your voice." And I will know to pray for you and for our marriage. You are not in this alone, I, your husband am here for you, don't shut me out. Remember our love, remember me."
Give her other thoughts to grab onto by which she can pull herself out of the sinking sand of temptation. Give her word pictures. Have her look into your eyes and remember that moment when she's tempted.
One power of temptation is the thought that it is so private that no one will know. Who can see into the thoughts in my head? God can, and every sin will be exposed for all to see. Have her imagine that she's right in front of you and in front of God, because God sees all even now, and we will all see all later.
Show her lots of love so that she can see the contrast between love and lust, diamonds and garbage.
