Reading just a tiny bit into what has happened - If you've done what you feel like you can, and he/she doesn't want to talk to you anymore, why not try and find him/her a job?

At least temporally, the easiest addressed problem is the unemployment. Talk to people you know, pull any strings you can, and try and get him/her an interview or a job -- that will easily show how much you care, and maybe you can THEN verbally say how much you care.
