anti structure? or experiment?

In the love song of J. Alfred Prufrock he places lines to release himself from the structure of the rest of his poem. He simply experimenting and experiencing freedom and once he tastes it he goes back. Such as those who go out side and soon after tastes the cold and retreat to warmth. This is exactly like his structure he gets out from his comfort zone and then soon retreats back. He follows this pattern throughout his life and soon after he dies.
