You are saying you just want her to hear her regret her decision. You didn't say you were hoping she would come home and restore the marriage. It's something you want to hear that isn't going to change the outcome of anything.
It's apples and oranges if you want her to regret her decision so you guys could reconcile. But you have stated you do not want to save this marriage.
You just want to hear her say she regrets this to make yourself feel better. We all wanted that. But almost all of us live without it.
