Is his reason he can’t finish college because of academics, or finances, or maybe this family issue? Maybe talking with you could help him, but it would depend a bit on the reason, and whether you have alternatives you can discuss with him. For instance, if someone is very I’ll, and needs him to be around to take care of them, that would be a disappointment for him, but a noble task, and something he could be proud of. If finances is the issue, would you be able to give him comfort to believe that he could finish in future, or would that not be an option? It seems to me he is in need of some hope. If you can find a way to give him some hope it would be beneficial to him, but I think also good for you. I think it would be good for you to mend that bond you had which has grown apart since childhood.
