Evio, Evio,
What are you doing?
You shouldn’t have asked, and he shouldn’t have answered the way he did.
And I get the "well, he was honest."
And I get the "it’s a trick to make you think he’s honest about everything."
Who knows.
I’m confused about the timing, though. You say it was after the 2001 affair, which was before you two were together. Was he thinking about her way back then, or more recently?
On to the substance.
Was he disrespecting you and his mate by cheating with mate’s wife? Of course he was, in the worst way possible.
Was he continuing to disrespect you and mate by thinking of her to further his arousal? Good grief, I don’t know.
Have you never fantasized about another man? Have you never gotten aroused watching a steamy scene in a movie? Is any of that disrespecting your husband?
He’s had sex with other women. You wanting to be his best in every category is understandable, but unreasonable.
Was there something about her that he found particularly arousing? Something about her looks, or actions? Maybe.
Does he wish your boobs we’re bigger/smaller? Maybe. So what. Maybe you wish he was bigger/smaller. So what.
Maybe he was just reliving the thrill of the conquest, or soaking himself in the validation.
Whatever it was, it’s faded for him.
You’re trying to compare, and you don’t even know what you’re comparing to.
Stop it.
He married you, after her. That’s what matters.
