should I ask him for more than fwb?

So I've been talking to this guy for nearly six months, we don't really talk about feelings like at all, the only deep conversation we had was months ago about his parents and that's about as deep as we got. I really like him but I'm scared that if I tell him that I have feelings for him it will scare him off. He had a bad relationship with his ex and (as his best friend tells me) "is scared of commiting again". But I'm over waiting and if he isn't going to commit I'd rather find someone else and build a relationship there. What do I do?
