lostone209,
On the evening of Monday, July 30th, you made your first post on SI. You now have 47 posts of your own on this thread which has grown to 10 pages. That means you have written and created almost 25% of this thread. It makes sense that you are a writer. You like telling us what is going on inside your head. You apparently aren't a listener though.
It is coming up on a week later, and you have been in conversation with a total of 69 different people on this thread. Yes, 69 people have taken the time to respond to what you have written. 69 people have given you their advice and their opinions about your situation and what you should do, and still you feel that you cannot do it. You don't want to hurt the AP (yes, I will start calling her the affair partner, not the other woman). You have not gotten the concept of going NC (mentally) with the AP. 13 days since you last contacted the AP. Every time you do that, it sets the clock back and you will find yourself in the mud pit you've chosen to stay stuck in for so long.
Imagine that 69 people got together and decided to help someone who was having trouble, be it drugs, alcohol, financial, spiritual, whatever. Heck, imagine 69 people got together for a barn-raising. Now imagine the one person they are trying to help spends the whole time trying to convince the 69 helpers that they have done everything to try to help themselves and it hasn't made a difference. This one person is you.
And finally, on page 10, you might be starting to see that you haven't been NC after all. This was mentioned by Bigger in the very first response to your OP.
Look, I know everyone moves at their own pace. But when you have so many people in one weeks time telling you the same thing, or very similar things, from so many different perspectives and nothing sticks...well, what is it about you that makes you resistant to hearing what is being said? Have you ever learned to really listen?
In no way do I think you are unintelligent, but you are not very good with regards to introspection. Writing is often about getting something out, isn't it? What about getting the truth out? Your truth. Not the truth you want to see, or that you want those around you to see, but the truth about what you have done to yourself and your BW. None of us gives a damn about what you might have done to the AP. She does not matter.
I think everyone here deserves a round of applause for sticking through this thread -

Yes, 69 people, and you sound like you are still trying to convince us of something, when you aren't even sure about it yourself.
So, as others have asked, maybe not is so many words, what are you doing here?
