FWIW, I would tell former AP's BH. Read some posts in the threads for those who found out years' later....
And I think the red flags WRT your current husband are HUGE....
Someone being dishonest from the get go.... engaging in sketchy behavior with another woman in the honeymoon phase of your M... the history of infidelity.
IMO, 7 years is not a very long time.
He has.... been a ‘stand up guy’, and I never had any reason to doubt him. Until now. Every discussion we have ever had about trust, fidelity, deal breakers, you name it, the responses have been exactly what I needed to hear to have no doubt about him. The way my kids took to him, and the mutual friends me shared, gave no indication of this.
Mine too. The total Boy Scout. Devoted in every way (still makes me wanna barf to hear those in our social circle tell me how they can tell he just "adores" me). Coached kids sports. VERY active in local community and school stuff.... the "go to" guy for ethical questions. And a serial cheater for pretty much his entire life.
Cheaters don't just change on their own (ask me how I know )
Cheaters don't magically become safe partners with time or by providing the passwords and GPS coordinates.
They don't change w/o serious introspection/reflection, honesty, accountability, empathy, etc. Even if they aren't actively engaging in an A, they are still just "dry drunks".
IMO, he needs some SERIOUS and deep dive IC, and until he does that, he is NOT a safe partner.
