Hi, BS here, trying to help and with respenct.
I think what he said was a coping mechanism. If he refers to you as "two different kinds of people", he doesn't have to acknowledge what you did really hurt him. It's his way of "chalking up" what happened, so to speak. It's how he's coping right now. He doesn't want to acknowledge how much pain he is in, and he certainly doesn't want to acknowledge it to you as he considers you the source of his pain. Consider when people do a fist pump (in movies etc) and say "As God as my witness, I will not waste one more tear on that man/woman." I don't know how else to say it or if I'm saying it correctly.
This may actually be a good thing even though I know it was hurtful to hear, because it sounds as if he is using it to make positive changes in his life. You said he looked good. Sometimes, we have to stop wallowing in the self pity however we can, and if this is his coping mechanism today, then rest assured, he will go back and review things. You have to move one step at a time forward. He is trying to move forward.
He referred to our marriage as "a silly mistake made by youngsters." I don't know if he is trying to hurt me or reassure me; whichever it is, it hurts me.
I can totally address this one because I heard it almost word for word from my WS!
In my case, it was my WS's excuse to carry out an affair and behave like a mean bastard. He did not want to face what he was doing to me because he knew it was wrong.
Your BS is using it as an excuse too, but he is using it to set aside his pain and focus on something else. If he believes your marriage is a "mistake", then what you did won't hurt is bad. I know it doesn't feel like it, but this is actually positive for you too because he doesn't want to demonize you. He wants to put you in the category as a kid who made a mistake.
Please don't tell him to seek counseling. even if he needs it. Here's the deal. I don't know what happened in your house, but in my house, my ex TOLD me I was crazy (paranoid, unbalanced etc..pick an adjective here) because he didn't want me to SEE what I knew was there (an affair etc). Now that it is all out in the open, and you are telling him to seek counseling out of concern, he is going to laugh and say "Ain't that the pot calling the kettle black?" I am not saying this to be ugly. But I can say that my WS spent so much time telling me I was crazy, that that would have seemed condescending to me.
Very gently, I certainly think you are remorseful and trying to work on your issues, but you cannot really think your husband was happy in your marriage because he didn't know the extent of the affairs. That was a lie. he as happy about a lie. He is re-evaluating his whole life with you as a lie. The good times. The bad times. He is dissecting it all.
I'm sorry to say this, but I don't think there is any saving your marriage. He is making steps to heal himself and move on. Please just do the best you can on healing yourself and being a great co-parent. We can all turn our lives around if we choose to, but he wants to turn his away from you. Be glad for what you had and move forward.
Sending prayers to both you and your husband. Divorce is hard, but sometimes, it is necessary, and sometimes it is not your choice.
I know that I am a vastly different person from all this happening to me, but in many ways, I am better than I was before. Stronger, more compassionate. We can all choose what we want to be. This includes you.
