I think your H needs to feel that he has no need to lie to you about what he feels and what he is exploring.
the fact that he is in a R with another woman speaks volumes to me. It would suggest that taking the 'next step' didn't feel right to him - that although a CD he is hetro.
As an aside, when I am depressed I withdraw from family and friends. It is easy to gloss over things with a stranger. One can put on a facade. I bet OW doesn't know the half of what's going on.
Make that road home obvious and 'safe' and welcoming. Your children are getting older so his CD will be less resticted at home as time goes on.....and once he has more freedom there is a possibility that he may not want to CD as often. Sometimes half the fun is in the secrecy, time limitaion of it all.
What your H does is not that uncommon. One of my BF's is married to a GP and she said that her H was surprised when he first started as a GP, at the amount of guys who would turn up wearing women's underwear underneath their outer clothing when they came for consultations.
I have seen on the news about the snow in Scotland - wrap up warm. It has even turned chilly here in the Midlands and we had sleet today. I don't want more snow - we had the best part of two months of it earlier!!!!!!
