Portia, How are you and your family doing? I hear you when you say taht you are in a strange spot. It sounds like you are detaching more and more each and every day. Yes, it hurts like the dickens because he's not been supportive and didn't want to see you. We can't "assume" that he is w/the ow once again, but time will tell on that one.
Portia, sometimes we have to let them go in order for them to grow up and find their way back to us, if that is what God has planned for us.
Drop the rope and let him go. He needs to learn that you will not be there to provide ego kibbles to him every time he needs them. He needs to learn that he had a wonderful person who was willing to share her life w/him, but he opted to toss it aside. He needs to face the consequences of his actions.
Sending positive vibes your way.
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.
