Why is gollum scared to appear friendly to bilbo ?

Gollum was a Hobbit, or rather a predecessor of a Hobbit, but was kicked out of his clan and forced to live in a cave. He became almost immediately obsessed with the ring; in fact he killed his friend who had originally found it. Gollum was weaker than Bilbo; the ring completely controlled him from the get-go.

So, the major differences were Gollum's weakness, and his living conditions which made him anti-social and changed his appearance due to the absence of light.

Bilbo definitely was affected by The Ring, just not to the same extent.
