I think you can accept his decision now. Try to move forward with your life in a positive way. Try to establish/maintain a positive and constructive relationship with him.
I think showing that you respect his feelings and his choices would go a long way towards reconnecting. Begging him to come back communicates that you are more concerned with your feelings than with his. (that's how I feel when my ex- bugs me to get back together.)
You can hold on to hope, but work on establishing a positive relationship now. You can still spend time together with your family without being together.
Maybe you can reconnect, but it will probably take time. Be patient.
