I am sorry about the meet up...but I am not at all surprised by her responses. The guilt is eating at her and she can't face you or the girls. She can't face the consequences of her actions and she doesn't want them to see her the way she is now. The person living in the past is her.
She won't wait until they are 30. Her father's death (when it happens) will send her in a tail spin.
For now, let it go...you've done all you can to bridge the gap. The ball is now in her court if she wants to see the girls.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
