Hello Kat,
Sorry to hear of this terrible news. I know how tough that is.
If you research 5 stages of grief, I think you will find it very useful. I think you are in deep shock and denial about what has happened. It's like you're trying to brush it under the carpet because you are so desperate not to loose your husband and family.
The problem is, this will probably cause your husband to loose respect for you.
You should be flaming raving whereas you have gone into autopilot damage control mode it would seem.
Please read this article, it's very good : -

The trust has been destroyed and it's needs to be earned back. A friend of mine once gave me a very good analogy. He said a couple are like and elastic band - strong and efficient. When somebody cheats, that band is snapped in half. You can tie it back together in a knot and it will be an elastic band again but it's not going to be as strong as it was. It's not 'how it should be'
I'm not saying you can't get over your husbands cheating but you can't just brush it under the carpet I don't think. It needs to be addressed properly
I think you need some good marriage counselling for sure and you need to take baby steps. For a start, you need to be 100% certain that this isn't going to happen again. With how you have acted he must be thinking "wow, I got let of the hook easy here"
How do you know he wont do it again in a year, 3 or 5?
I hope this gives you a start.
