Forever a FWB or are we more?

My FWB has been going on since June of 2014. But he still won't commit. He says he cares about me and I'm important to him. I've met his family and his friends but he's still so scared to call me his girlfriend.
Oh by the way he still lives with his ex's, who cheated on him, dad (his mother passed and he had no where else to go.)
