I am so sorry the bomb drop was the LBS worst nightmare.

I can so relate to what you wrote above about your Hs need for ego stroking, etc. My H is like that and that is why I worry about over friendly FFs. Anyway, I think you guys are doing great communicating and trying to get to the reason for why he has had the EAs. Without the cause, one has no idea when/if it will happen again. My H never confirmed his past possible EA but I do think that is was not appropriate and we have never discussed the whys.

I am sorry that you found yourself back in the EA but I do commend you for coming clean and also trying to find the cause and work with Rottzilla on the BB.
Hang in there both of you, SP
