Tessa, I have to agree w AS. It doesn't sound like forward progress--just a cycle of the same stuff over and over.
It does sound like you are doing some nice 180's & he is responded though regarding some of the things you say/don't say.
Having said that at some point the interaction between he & OW is going to change or you may get tired of tolerating his "hero" interactions w HER and then running back to you for some great sex.
It might be beneficial to "try something new" by NOT having sex w him as he continues these interactions w HER. Unless you are okay w their R as it is for now, of course. R u ready to establish some boundaries or do you feel you are okay w things as they are? b/c your H is DEFINITELY CAKE-EATING!!!
