I am so happy to come here and read that your vacation was wonderful. So many new memories and yes, your son is now a man and your X has missed out on all of the important/special times in your son's life. Such a pity.

You and your son have so much to be proud of!

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.
