Mike,
You stand a good chance of making a great marriage with your W. You have that level of awareness, which is great. I thought my H did. He has said things to me like, "she was filling a void" and "I'll never love anybody but you" and "I want to spend my life with you" and "we can make it thorugh this". But then he goes back to OW after saying all those things. So, i'm at a loss.

You need to remember what you just wrote everytime you think you want to go back to her. Think of the great M you can have. Figure out how to fill the voids in your M with your W.

How long did your A last?
