Most times, when the door to a marriage is closed, the room was already empty.
You've been through the hard part and survived well. You have felt the grief of the loss of the dreams that will never be. Now you get to start the new beginnings, a time filled with wonder and hope and dreams that will be greater than any you have known before...because they are "your" dreams and you now hold the key to your own happiness. You did all along and didn't know it until now.
Hugs and prayers for you and your child. May the world be filled with sunshine and happiness for both of you.
