How can I help my boyfriend ?

My boyfriend is really shy half the time he doesn't talk to me. He had his house broken into when he was younger someone snuck into his room and tried to murder him. He's also terrified of the dark. He still uses his nightlight we keep the hallway light on and the doors locked at night. Some nights he wants the tv on. Me an him are in a band the only time he's talking when he's singing or were performing. He's the youngest band member too I'm the oldest. Sometimes he cries in his sleep or he cries to sleep. How can I help him feel better ?
