I choose school over my mom

Ashton loves school so much that he wants to live there. I told him how much I would miss him and about all the things that he would miss if he didn't live with us, but all he said was, "I wish they would put a bed in my school." Now he won't even tell me about his day. Today I asked him, "Can you tell me what you did at school today?" He said, "I'm not having any discussions right now." There is no way I can ever let him leave and move away for college. If he is not going to be "having any discussions" on the 7 minute car ride home, then there is no hope for a phone call when he is away.
