This is qtx411's thread, but I did want to respond to what Cld said.
"I will be there when she comes back to her senses."
You are still under the impression that this is a momentary lapse of insanity. It may and it may not be. Either way it's what your W believes she needs to do in order to grow and be happy. It has become a part of her. By you constantly denying it with your reasoning about her past, etc. shows that you're not trying to understand where she's coming from. Put it this way, the next OM that comes along is going to do exactly that. Listen to her and understand her POV. You don't have to agree with what she's doing but she has a right to do so.
qtx411, it's up to you what you want to do, but it comes down to you. If you don't want your W any more, then move on with someone else. Although I would suggest learning to be happy without someone so your happiness isn't tied to another person.
