I actually love your comment.
You know what, OP, I really am one of those people who knows life isn't black and white and people make mistakes, they can change, etc., etc.,
My DH had an affair for 5 months, I discovered it two years ago after looking at his phone (it made a noise, I checked it, not snooping) and I have forgiven him.
I'm sure if I came on here and posted about how much I love him, how 'perfect' he is, how he is affectionate, supportive and all that stuff I'd face a lot of derision.
But, I don't do it, because I don't need it. I'm happy and secure in the decision I've made. Unlike you, I'm not on here looking for that one poster in a million who's going to tell me my relationship is brilliant (when all the others are saying WTF are you doing) and for the reassurance I have nothing to worry about, like you seem to be here.
The reason:- DH has done everything he possibly could to make amends.
He doesn't come out with shit like, I was bored, there wasn't enough sex, she focused on the kids more than me, I felt ignored.
He went for counselling, changed his behaviour around certain things, admitted to his family what he'd done, encouraged me to tell mine for support, has never run away from his behaviour and blamed me for the crap he's put us through, has stayed for the initial, constant pain, anger, humiliation, the latter grief and sorrow and the questioning of every little detail. He didn't blame our relationship, he blamed himself, totally and utterly.
And he's still here two years later, and I know deeply ashamed of what he did and he would never put me (or him!) through that again.
As for your soon-to-be DH, he hasn't addressed any reasons for why he cheated, he only did it because he wasn't getting enough, allegedly. And, despite the fact he cheated several times on her, it was all his DW's fault. Yeah, right...
Good luck. You'll most probably need it.
