Ophelia, I'm sorry about your discovery (OW). It's a hard pill to swallow.
Your H is probably thinking he's a rock star now with the positive changes because he's living like one with the credit card debt and OW. That lifestyle has a way of burning it's self out. He's eventually going to wake up and realize he's living with his parents at 29 years old. That should motivate him to get his financial affairs in order and eventually realize the mistake he's made.
You stood by the "old" him and he will think of that sooner or later.
"It is curious that physical courage should be so common in the world and moral courage so rare." -Mark Twain
