I agree the honorable thing to do would have been to end things with his wife before trodding onward with the past/new, old love. I don't see him gloating about that, either.
Perhaps, Sky Blueback, seeing your strong feelings on the subject can also help put things into perspective for the guy... provide him another way of seeing things. I feel somehow relived that my feelings on this subject are not so hot... they're removed from the scene, as it is not my own. Was a time when my anger at the seeming injustice of the situation would have prevailed. I thank you for expressing yours as I commend soccerdad for expressing his particulars.

Personally, I think soccerdad is trying to figure it out... he's aware of his mis steps, and seems weary to make any more.
And, yes, as another pointed out, we don't really know half the story here...
From what I can tell, he wants to clean things up, somehow... Isn't that a good thing.
Deception never works, that's all I know.
