Thank you both for your replies.

The EAs (online flirting) and PA (which was discovered days ahead of it becoming physical but he admits it would have)were dealt with in perhaps the worst possible way - I didn't tell a soul and never worked through my resentment. Often since I have behaved untrustingly. Not helped by the fact that although he apologised at the time he has only expressed the extent of his regret since the recent BD. I think to have heard this a few years ago would have greatly helped me to forgive. H appears sincere when he says no-one else is involved now and I don't have any reason to suspect otherwise at this point.

I have been trying to GAL and have joined two classes, started regularly going to the gym and seeing a friend more often. This started before BD as I'd worked out that I needed to do this especially now the kids are getting more independent(teenagers).

I'm not sure why he said he didn't respect me? But looking from my end I have been very down, critical and clingy as I sensed him withdrawing in recent months.

I have been to IC but after a few sessions the C advised that we couldn't go much further without H on board. And yes I am reading and re-reading DR which kind of raised my question about whether I should continue to work with him. It makes going mysterious tricky but provides lots of opportunity for contact about things other than the R.
