Samwise's conflict within the journey of the ring

In the book Lord of the Rings: The Followship of the Ring Samwise Gamgee (ideally referred to as Sam) is pulled into the quest concerning the ring by one of his closest friends, Frodo Baggins. He did not intend on going on this quest in the first place, but when Frodo (who he deems his master) feels he needs to go on this quest the only thing he feels is right is to follow him. Multiple times through out the chapters after their departure from from the shire Sam has conflicting thoughts weather or not he should return to the shire, he is homesick, he would not like to experience the dangers of the world and would prefer to stay at his safe home in the shire. 

Once the hobbits arrive in Rivendell with Aragorn, whom they met up with in Bree and is now their guide, they feel calm and at peace. Sam always dreamt of meeting the Elves and going to Rivendell, but it doesn't quite feel like home. At this point in the quest he feels that the ring is safe in Rivendell and they can leave it there and return to the shire, he thinks that his quest is over, unfortunately it isn't. Then, when the counsel of Elrond comes around, they decide that the ring cannot stay in Rivendell as, although it would be hidden and mostly safe, the threat would not be eliminated.

The ring is to go with a company of nine companions, equal to the nine ring wraiths of Sauron, during the council of Elrond nobody stood to take the ring to the mountain of doom. When nobody else would take it Frodo stood to the challenge and agreed to take the ring to Mordor, the first six companions were chosen during the council, one person from each free race of peoples of middle earth, for Hobbits it was Frodo the ring bearer, for men it was Aragorn and Boromir, for dwarfs it was Gimli, and for elves it was Legolas, Gandalf the wizard would act as their guide. Three more members were left to be chosen, Elrond suggested that he send with them elves of his house as the remaining three, Sam was to be the seventh member of the group, Elrond could not argue with this as he said in the book "You at least shall go with him. It is hardly possible to separate you from him, even when he is summoned to a secret council and you are not."

Elrond permitted Sam to go along with the fellowship of the ring, the final two members, who also begged to go along, were Merry and Pippin, two more hobbits. They begin the journey and Sam immediately starts second guessing himself when they mention going back to Rivendell because the route they were planning to take, he begins to think they also might second guess the quest and go back to Rivendell, but they decide to take a more dangerous route through the mountain Moria, as they were previously planning to go over it but were blocked by a snowstorm. While going through Moria they lose their guide Gandalf to a Balrog of Morgoth, a creature that dwells in the deep parts of mountains, made of both shadow and fire. The company is unsure where to go next as they have lost their guide, they decide that the nearest safe place is Lothlorien.

As they enter Lothlorien, another elvish city, as it is a pure place of joy, their grief is momentarily removed while they reside that place. Sam feels safe here, he always loved the elves and loved to see what he called "elf magic" but he still misses his house and mentions how he loves where he is but he still misses the Shire. When they meet Galadriel "the lady of light" who rules over Lothlorien, she speaks in their minds, she tempts them, she temps Sam, she ask him if he would go home if she brought him safely home. Later as they discuss everything she said to them, he says that, if he could go home, and if Frodo would go with him, he would leave and go home. This shows his commitment to Frodo and how much he feels responsible for him and how much he cares about him.
