Before the First Curse
It is revealed in an episode of Once Upon a Time, "Think Lovely Thoughts",  that Peter Pan was originally Rumplestiltskin's father, known as a man named Malcolm. Young Rumplestiltskin's father most of the time had caused great pain, mostly because Malcolm was a conman. Once, a man tried to kill Malcolm, but Rumple intervened from the man doing furthur damage to Malcolm, but he robbed them, leaving the Golds penniless. Rumple then goes to live with spinners while Malcolm leaves apparently looking for work. During his time there, the spinners teach him how to spin wool. When Rumple learns that his father isn't really looking for work, he decides to take his father to another land where no one knows them. He takes the magic bean and they land in Neverland. However, after realizing that he wouldn't ever be free, Malcolm gave up Rumplestiltskin for youth, forcefully. This left Rumple heartbroken and he was left raised by kind-hearted spinners.

Furthur of his early life was also detailed in the episode "Manhattan". Sometime later he married a woman named Milah and they sold wool as a living. While Milah was pregnant, he left after being drafted for the ogre wars and looked after a child seer. She warned him that his actions on the battlefield will leave his son fatherless. Rumplestiltskin purposely breaks his leg. When Milah finds out of his cowardice, she turns on him disgusted while handing their son over to him. Rumple looks down at his newborn child son and decides that he will never leave him alone

Years later, Rumplestiltskin made the deal with the devil when his son Baelfire was bitten by a poisonous snake. Fendrake sees that Rumple is indeed desperate to save his son, and allows him to keep the antidote in exchange of his second-born. Rumple takes the medicine and allows Baelfire to drink it, thus becoming able for Neal to be fully recovered.

Belle

Although he loves his power, he also loves Belle. However, his kisses to her never wakes Belle up, mostly because her father is too selfish to wake her up.
