I think that Bilbo did indeed have a "Gollum" side to him, but he lived in different circumstances, which is why didn't allow his Golumn side to rule. Bilbo was sourrounded by hardy, faithfull, and encouraging friends. But remember when he gained The Ring, the first thing he did was lie about it, that's The Ring's influnce on bringing "Gollum" to the surface. Bilbo, unlike Smeagol, didn't need to become a Gollum in ordr to protect himself. Smeagol had been an insecure and needy person before he had the The Ring, and The Ring merely expounded upon that. Because Bilbo was a secure person, The Ring didn't have the easy time in seducing Bilbo that it did with Smeagol. In concluson: under different circumstances, Bilbo too would have become Gollum.
