lala, I would say that you continue on just as before, that is, you focus on you, GALing and making you a better YOU. Additionally if you get back to the place where you are nuturing the friendship with your H then do so without expectations.
The other mental exercise you have to implement is not letting your mind run away with itself, meaning concocting what your H may or may not be doing when you are not with him, this is the detaching part. Easier said than done for sure.
As far as this "work" friend goes, you don't know anything and you have no reason to suspect anything. You are not even back in the house yet, wait until you get back and get a routine going and there is some interaction with your H.
Right now you have a great list of things you are going to do for YOU. Don't worry about him right now, again easier said than done I know.
If and when you and your H are spending time together again and if the time is right you may be able to "set a boundary" with him. I am not suggesting that you do this now and there are many more experts on these boards that could advise you better than me, but you could say something to your H like:
H, I would prefer that you not talk about your relationship with your female co-workers given your history with OW#1, I feel hurt, betrayed and uneasy when you talk about _______(co-workers name).
If you and your H get to a point where you guys agree to work on the M then it may even be appropriate to give your H a copy of "Not Just Friends" by Shirley Glass. IMO you would only do this within the context of working on the M, someone else may want to chime in here...Puppy, Mach, Allen????
You don't want to come across as trying to fix him, but after hiding an EA for 7 months, having female "good" friends is not going to "get it" in a reconciled M. EA is cheating just as much as a PA is.

Expose yourself to your deepest fear; after that, fear has no power, and the fear of freedom shrinks and vanishes. You are free.
