Ok, I have to say this. I'm worried about the pressure your S feels right now. You are basically asking him to choose whether he wants to see his mom anymore. Do you really want to have that forever in his head that he was the one that decided to leave his mom? Whether it is the right choice or not, I'm not sure any kid should have to make that kind of decision. YOU can make that decision and explain why and he can listen and agree, but to have HIM be the decider......I see long term effects of this. You are the parent, you see what you need to do for the better of the family, and YOU make the decision. But, he is being pulled by your W saying "you like it here, you like it here" and you saying "you wanna get outta here?" and that puts him in the middle. It sounds like he is a mature boy, and does have an opinion about this but you know what I am saying? Maybe even to say something along the lines of "I know how you are feeling and thank you for telling me your thoughts on moving. Ultimately, I will do what I think is best for the family, and this decision is not on your shoulders. This is for a parent to decide. I'm sorry you have had to deal with all of this. Just know that both of your parents love you, you have nothing to do with our problems, and we will always take care of you." Or something.
