What a thread AJM80! You are handling this all very well and have inspired me to do better in my sitch with regards to my WAW and D.
Someone on one of these posts introduced me to Dr. Robert Glover's book "No More Mr. Nice Guy." A lot of the info on 'Nice Guy Syndrome' applied to me and I suspect it might apply to your H also, based on your descriptions of him. Main thing is he's a liar - but is lying to himself more than anything else. One thing that tipped me off was how he seems to believe he can "help" OW stop stripping - classic NGS, always trying to solve other peoples problems.
As far as the OW, I can't imagine it will last much longer, if isn't not over already. I believe in my sitch, a lot of what my W does is based on some perceived notion that if she doesn't ride this out longer, then it will appear as if her decision to leave was wrong and that she made a mistake - but then again, that could just be my NGS working to justify something crazy in my mind. But, I do know she has a problem with being perceived as "wrong."
With regards to what you should do next with job, move, D, etc., I'll give you the same advise you gave me over on my thread: "you need to be very honest with yourself about what your goals are for you and for your relationship." Once you decide for sure, work towards that. The rest is irrelevant.
