He was a good influence on their lives. He entered their lives when the boys were little, all pre-teens. Their real biological father was abusive, alcoholic etc and my DH showed them a life that was different and positive.
I do think it is special that he wants to reconnect with DH knowing that it will be connecting with me. That says something, too.
I know I will be anxious about it until it happens but will do my best.
Thanks for all your good thoughts.
