Thank you all for your responses and advice. Okay some points of clarification:
I like that. The thrill of the hunt. But I'm not looking for variety. The woman at work is very similar to my wife in so many respects. What I crave is attention, affection, and someone who listens to me without argument or being belittled. I wasn't hunting for it, but it showed up anyway.
I might be totally blind, prideful, insane and out of touch with reality. She keeps telling me I am. I have been through counseling twice through LDS family services and to my bishop.
In counseling it came down to me telling all I was able to tell and the counselors saying I was basically normal and my problems could only be resolved if my wife would come in with me. Her response, "You have the problem. I'm not going to counseling."
With the bishop I confessed all of my sins (this was before the affair) and he eventually told me he received revelation that I was forgiven of which I received a personal confirmation.
I know divorce is wrong. I don't want it. I can live with the emotional and physical abuse. I think it's less than ideal that my children learn that when you have interpersonal problems the way to deal with them is screaming, fighting, hitting, abandoning etc.
So after 5 years of doing what you suggest. Work on myself and hope she'll come around and reciprocate. That is the only option? Wow oops. I definitely don't have the Spirit right now.
So I need to repent and get the Spirit back so I can have patience for however long it takes for her to decide to come to the table. I'm sorry my tone is sarcastic. I better take a break. My jaw is still sore.
Edit: Okay I've calmed down. I apologize for being so rude and disrespectful. I do appreciate the time you have given me. My rudeness is unjustified. By way of explanation though, it is very difficult for me being in so much pain for years and to hear well just endure to the end. Especially when the end could be an escalation of violence that leads to inordinately traumatic events for my children.
