You have chosen to be hurt by her actions. You can choose differently. Advice to seek a lawyer, reach out in anger, accuse her of being the selfish one, and so on will only make matters worse and intensify the consequences of your first choice. The only solution is to love your daughter unconditionally. That may be your best choice.

The easy thing to do is to be angry. The hard thing to do is to love. Easy rarely means best. Hard almost always means correct.
Best always,
