See, by you saying your W only knows her own way of doing things you are still fearful of her reaction. If she feels ignored, well, there is nothing you can do about that. You cannot make her feel something different.
She wasn't all that concerned about YOU feeling ignored when she was having her affair. In fact, she had little care about your feelings then. Yet somehow you found resources to help you through. If your W is serious eventually she will go looking for resources just like you did. If she doesn't then nothing will ever change.
