Your H needs to realise that an OW would not give him any more than he has now - infact it would give him a lot less.
My H like yours was not very experienced. I have said many times before but I will say it again - I was very lucky with the timing in my sitch in that my H had been having the A for 18 months by the time he told me about it. It had pretty much run it's course and he had been able to see for himself all the complications and down siides as well as get over the majority of the excitement / adrenalin rush. Once he admitted it he started to see it for the seedy mistake it was. Somehow your H has to realise that what he would get elsewhere would be so much less than what he gets with you.
He needs to know that happiness is wanting what you have NOT having what you want, (not that he seems to know what he wants!!!). saffie
