Can a marriage survive two affairs?

"Why is he still sad? Is it normal? Am I just expecting too much? Is it normal and is he just telling me too much?"

Uh that's why you need to go to C for this. Instead of guessing these things, you need to discuss this with him. If he refuses to, then he's not committed. Just because he's there doesn't mean he's "there".

All of these thoughts are red flags and if they go unanswered, this same situation will happen again.
