I am so sorry. I am having similar issues with my DD, who has been admitted to some great places, and can't decide on any of them. She just says "I don't want to talk about it anymore"
I quite honestly think that kids have too many choices now - if they got into five of the 12 schools they may have applied to! I only had one choice and that was the affordable state school back in my day. The choice was easy.
I did talk to a relative who told me that kids sometimes can't make the choice and you have to make it for them. We also sat down and talked finances and what was affordable.
You may have to make the best choice. Hopefully, he will just go and learn to love where he goes. I know in my DD's situation, none of the schools in the affordable range are bad. All good. Just got to go to college.
