Hello amy,   I just re-read your Question, and want to focus on the idea that your boyfriend has withdrawn from you and his family.  The isolation is a symptom, a hallmark, of the illness.  When he gets out of the hospital, I recommend he join a day program where he can connect with other people in a supportive environment where there is daily group therapy, art therapy and also the patients can have lunch together.  That is an option.  I trust you are visiting him in the hospital.  In one of his lucid moments, if you feel he is able and amenable to hearing you, perhaps you could suggest he find a day program when he gets out of the hospital.  Sometimes, that's the best option.  Because to withdraw isn't healthy, and a lot of times, "society" doesn't welcome back into the fold a person who's been released from a hospital, but the counselors and staff at the day program will open their arms wide.   It will take effort; however, your boyfriend can have a full, productive life if he makes his recovery the number one focus.   Best, Chris
