Portia, I personally think you should hold off contacting him. Why? Because he's jumped from you to the ow and is now trying to rope you back into his drama. Your man needs to learn to live on his own and see what he's missing when it comes to you. He can't do that if you are staying in touch w/him. He needs to appreciate what he had and lost. Now, if something should come up in the way of your family member, then yes, I would contact him. Otherwise, stay the course.
Your man needs to grow up.
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.
