You really have overturned your situation in less than one month. You are so smart not to engage in any arguments because they stay very sensitive for many months. I learned like you to let it go if it doesn't really matter. But with time they are getting more open minded.
Stay tuned to your situation, you are going right now through the phase called "hysterical bonding", it lasts for a few weeks then the real work starts. You will see if he is really remorseful and taking the blame for his actions and shifting the blame from you to him for the long term and, you how you will be dealing with resentment once everything will go back to "normal". I am not trying to scare you in anyway, but when the resentment waves hit me I was quite surprised and it brought back some bad memories, that anger was so tough to deal with, it was not related to any of his present actions, it was just like my body was possessed by those thoughts. I am quite over them but they are still nagging me sometimes. That's why keeping GAL is so essential. I really hope everything will work fine for you. I am just trying to give you some input on what lays next.
Bluwave described pretty well what she is dealing with right now, and I do/did share most of her thoughts at one point. It helped me to understand that I was not the only one with those issues, but those also should pass at one point. I am trying to live with my mind set on the future, because I cannot change the past and also it hurts too much. I have to let it go and set up new standards and boundaries for my new marriage, the old one being dead.
Have wonderful week end!
