This wasn't about being a selfish mom. She didn't want to divorce Big Kev b/c . . . she didn't want to. She probably wouldn't have if the story had not broken. She's not the first wife to hush up an affair or side baby. She loves him and is comfortable with him from their decades together.

However, she seems to be in a good space here. It's probably a relief to not have to overlook Big Kev's bs anymore, and it probably feels good to just come clean and be at peace with how events are evolving.
