Can my boyfriend qualify for SSI and How would he apply?

We had a psychiactric evaluation done on February 27, 2009 (CPS made us do it and that story is too long to tell and irrelavant to this question). In this evaluation it says that my boyfriend is learning disabled and doesn't look well. He appeared to be a submissive individual to the point where he is backwards in terms of social skills. The psychiatrist says that my boyfriend has reasonably good understanding of the vicissitudes of parenting. The rigidness comes from a characteristic of learning disabled clients. He graduated from Neil Reid High School and was in special ed. for all of his acedemic years. He can't get a good job because he can't understand tests or read very well or very fast. He is very bad at basic math. When we have a conversation sometimes it's frustrating to hear the mispronunciations of words or misuse of sentences or phrases. However he is smart about many other things such as computers to a point, and video games are like his safe haven. He is 32 years old. I'm like his second girlfriend. I try to be supportive of his disability and he wants me to go to college to earn my degree before he goes because he is afaid to take too long and use too much money on school. BREFORE ANY OF YOU HAVE A RUDE OR SMARTA** COMMENT NO HE IS NOT RETARDED HE HAS A LEARNING DISABILITY.
