I want to keep it civil but still I have the desire to lash out and tell her to leave me the fk alone already and leave my D alone if she cared so much she would have made a better effort to stay in contact with her. Instead she NEVER calls her, now does not answer her calls, and blocked her on FB.
If you choose to respond AND let her into your D's life. Then she needs to know that she will have to be for the duration of your D's life. She needs to be able to have open contact and not pull the underlined $h!t on your D again. If she can't or will not commit to that then it's in your best interest to keep your D out of this and CLEARLY tell your Ex to honor your wishes on what's best for YOUR Daughter. That's my opinion.
