I will say, though, that my H did some things that were absolutely horrible while we were 'separated' (in his imagination). He regrets that today and has said he would not do it over. Some of it he even hasn't really admitted, although I have read the e-mail exchange with his L, so there's no doubt what was said and attempted. And yes, it makes me wonder if he could flip into a person with absolutely no allegiance to me or our M again, without me knowing.
When it comes to recording - I'm sure what you said is not so bad in the big picture. Everyone makes mistakes and gets emotional at times. Everything will pale in comparison to what he has done with his A. He is probably feeling very threatened by the fact that you know who the OW is and that they are at risk professionally.
I hope you can stay calm during any future interaction, you will probably not be able to have absolutely everything go via a L.
Again, so sorry that it has taken this turn.
