Itsy, If you truly want to extend the invitation, try doing it yourself. It would show him just how far you've come. Remember....actions speak louder than words. If he opts not to attend, at least you will know that you put forth the effort for the family and not just you.
I'm doing very well. Thanks for asking. Yes, you had a very rough time, but you are doing so much better now.
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.
