She’s an adult and I assume she’s mentally capable. Just support her and when/if she ever regrets her decision, she’ll have you around to lean on.
If you openly hate on her decision or shame her for it, you’re only going to drive her away or make her even more firm in her choice.
I’m not sure how you interpreted my comment to mean that “Mommy and Daddy” would need to pull her out. I only suggested they be there with love and not shame so she doesn’t stop speaking to them.
