Hi formyboys...I remember you; I don't know that I posted on your threads, but I remember reading your story.
I'm SO happy to hear the excellent update on your son! Sounds like a complete turnaround for him so far and the move may be exactly what he needed.
I don't have kids, but I do have teens in my life and memories of friends from that age. Your son is 15...he's old enough to make decisions about his relationships. He may not really want to communicate with his dad much right now. He may see the choices his father has made and be wanting to distance himself from that. It's up to him to decide what kind of relationship he has with his father, not you. In my state, he is at the age where the courts start deferring to the child about custody issues because they are old enough to understand & make good decisions, especially if they have a parent (like you!) giving them good guidance.
So glad you're back!
