There will be plenty of time to think about those questions later, and to come up with answers and solutions for you. Now is the time for you to sit back and relax and enjoy the afterglow OF A JOB WELL DONE.
That was INCREDIBLE.
Calm, cool, detached, civil. I was going to give you a "B+" because you let him draw you back into some R talk in the middle, but the way you closed it back out at the end and re-took control was fantastic, so let' make that an "A-."
Here's another line you'll like, and TRUST me, you'll have a chance to use it very soon, perhaps even today:
The next time he asks you what he should do?, (by the way, that is VERY much "script"), say:
"This is your mess -- you have to clean it up." (or " . . . you get to clean it up.")
Don't get into any more R talks with him right now, and DON'T do the "Don't you think that's disrespectful?" thing. Remember, "You can't teach an adulterer." Little TRUTH DARTS, well-timed and landed, are the most you can hope for at this stage.
By the way, this stage is CRITICAL. Don't go all "melty-woman" (I was sooooo glad to see that you didn't!), and DON'T pursue him.
Don't try to fix his issues for him, nor even shelter or cushion him from the consequences of his infidelity.
Do not judge him by ANY words that he says to you; only judge him by his ACTIONS, over time.
When his actions align with his words, over time, you will know that what you are getting from him is the truth. I suspect he's still at least a couple of months away from being ready for that, although I never discount what God can do.
So rest, Belle. Savor your newfound strength, courage and determination. Know Who was the Source of it, and thank Him today. Learn the fine art of the "I'm not sure about that, I'll get back to you" response, and use it for as many days -- or even weeks -- as you have to.
You don't have to decide anything today.
So incredibly proud of you; that was NOT easy, I know.
